|

|
||||
On November 2016, only 4 months after raylib 1.5, arrives raylib 1.6. This new version represents another big review of the library and includes some interesting additions. This version conmmemorates raylib 3rd anniversary (raylib 1.0 was published on November 2013) and it is a stepping stone for raylib future. raylib roadmap has been reviewed and redefined to focus on its primary objective: create a simple and easy-to-use library to learn videogames programming. Some of the new features:
|
||||
|
||||
Complete raylib Lua binding. All raylib functions plus the +60 code examples have been ported to Lua, now Lua users can enjoy coding videogames in Lua while using all the internal power of raylib. This addition also open the doors to Lua scripting support for a future raylib-based engine, being able to move game logic (Init, Update, Draw, De-Init) to Lua scripts while keep using raylib functionality.

Completely redesigned audio module. Based on the new direction taken in raylib 1.5, it has been further improved and more functionality added (+20 new functions) to allow raw audio processing and streaming. FLAC file format support has also been added. In the same line, OpenAL Soft backend is now provided as a static library in Windows to allow static linking and get ride of OpenAL32.dll. Now raylib Windows games are completey self-contained, no external libraries required any more!

notes on raylib 1.7
|
||||
-------------------
|
||||
|
||||
On May 2017, around 6 month after raylib 1.6, comes another raylib instalment, raylib 1.7. This time library has been improved a lot in terms of consistency and cleanness. As stated in [this patreon article](https://www.patreon.com/posts/raylib-future-7501034), this new raylib version has focused efforts in becoming more simple and easy-to-use to learn videogames programming. Some highlights of this new version are:
|
||||
|
||||
More than 30 new functions added to the library, functions to control Window, utils to work with filenames and extensions, functions to draw lines with custom thick, mesh loading, functions for 3d ray collisions detailed detection, funtions for VR simulation and much more... Just check [CHANGELOG](CHANGELOG) for a detailed list of additions!
|
||||
|
||||
Support of [configuration flags](https://github.com/raysan5/raylib/issues/200) on every raylib module. Advance users can customize raylib just choosing desired features, defining some configuration flags on modules compilation. That way users can control library size and available functionality.
|
||||
|
||||
Improved [build system](https://github.com/raysan5/raylib/blob/master/src/Makefile) for all supported platforms (Windows, Linux, OSX, RPI, Android, HTML5) with a unique Makefile to compile sources. Added support for Android compilation with a custom standalone toolchain and also multiple build compliation flags.
|
||||
|
||||
New [examples](http://www.raylib.com/examples.html) and [sample games](http://www.raylib.com/games.html) added. All samples material has been reviewed, removing useless examples and adding more comprehensive ones; all material has been ported to latest raylib version and tested in multiple platforms. Examples folder structure has been improved and also build systems.
|
||||
|
||||
Improved library consistency and organization in general. Functions and parameters have been renamed, some parts of the library have been cleaned and simplyfied, some functions has been moved to examples (lighting, Oculus Rift CV1 support) towards a more generic library implementation. Lots of hours have been invested in this process...
|
||||
|
||||
Some other features: Gamepad support on HTML5, RPI touch screen support, 32bit audio support, frames timming improvements, public log system, rres file format support, automatic GIF recording...
|
||||
|
||||
And here it is another version of **raylib, a simple and easy-to-use library to learn videogames programming**. Enjoy it.

i. "Reproduce" means to make copies of the Work by any means including
|
||||
without limitation by sound or visual recordings and the right of
|
||||
fixation and reproducing fixations of the Work, including storage of a
|
||||
protected performance or phonogram in digital form or other electronic
|
||||
medium.
|
||||
|
||||
2. Fair Dealing Rights. Nothing in this License is intended to reduce,
|
||||
limit, or restrict any uses free from copyright or rights arising from
|
||||
limitations or exceptions that are provided for in connection with the
|
||||
copyright protection under copyright law or other applicable laws.
|
||||
|
||||
3. License Grant. Subject to the terms and conditions of this License,
|
||||
Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
|
||||
perpetual (for the duration of the applicable copyright) license to
|
||||
exercise the rights in the Work as stated below:
|
||||
|
||||
a. to Reproduce the Work, to incorporate the Work into one or more
|
||||
Collections, and to Reproduce the Work as incorporated in the
|
||||
Collections;
|
||||
b. to create and Reproduce Adaptations provided that any such Adaptation,
|
||||
including any translation in any medium, takes reasonable steps to
|
||||
clearly label, demarcate or otherwise identify that changes were made
|
||||
to the original Work. For example, a translation could be marked "The
|
||||
original work was translated from English to Spanish," or a
|
||||
modification could indicate "The original work has been modified.";
|
||||
c. to Distribute and Publicly Perform the Work including as incorporated
|
||||
in Collections; and,
|
||||
d. to Distribute and Publicly Perform Adaptations.
|
||||
|
||||
The above rights may be exercised in all media and formats whether now
|
||||
known or hereafter devised. The above rights include the right to make
|
||||
such modifications as are technically necessary to exercise the rights in
|
||||
other media and formats. Subject to Section 8(f), all rights not expressly
|
||||
granted by Licensor are hereby reserved, including but not limited to the
|
||||
rights set forth in Section 4(d).
|
||||
|
||||
4. Restrictions. The license granted in Section 3 above is expressly made
|
||||
subject to and limited by the following restrictions:
|
||||
|
||||
a. You may Distribute or Publicly Perform the Work only under the terms
|
||||
of this License. You must include a copy of, or the Uniform Resource
|
||||
Identifier (URI) for, this License with every copy of the Work You
|
||||
Distribute or Publicly Perform. You may not offer or impose any terms
|
||||
on the Work that restrict the terms of this License or the ability of
|
||||
the recipient of the Work to exercise the rights granted to that
|
||||
recipient under the terms of the License. You may not sublicense the
|
||||
Work. You must keep intact all notices that refer to this License and
|
||||
to the disclaimer of warranties with every copy of the Work You
|
||||
Distribute or Publicly Perform. When You Distribute or Publicly
|
||||
Perform the Work, You may not impose any effective technological
|
||||
measures on the Work that restrict the ability of a recipient of the
|
||||
Work from You to exercise the rights granted to that recipient under
|
||||
the terms of the License. This Section 4(a) applies to the Work as
|
||||
incorporated in a Collection, but this does not require the Collection
|
||||
apart from the Work itself to be made subject to the terms of this
|
||||
License. If You create a Collection, upon notice from any Licensor You
|
||||
must, to the extent practicable, remove from the Collection any credit
|
||||
as required by Section 4(c), as requested. If You create an
|
||||
Adaptation, upon notice from any Licensor You must, to the extent
|
||||
practicable, remove from the Adaptation any credit as required by
|
||||
Section 4(c), as requested.
|
||||
b. You may not exercise any of the rights granted to You in Section 3
|
||||
above in any manner that is primarily intended for or directed toward
|
||||
commercial advantage or private monetary compensation. The exchange of
|
||||
the Work for other copyrighted works by means of digital file-sharing
|
||||
or otherwise shall not be considered to be intended for or directed
|
||||
toward commercial advantage or private monetary compensation, provided
|
||||
there is no payment of any monetary compensation in connection with
|
||||
the exchange of copyrighted works.
|
||||
c. If You Distribute, or Publicly Perform the Work or any Adaptations or
|
||||
Collections, You must, unless a request has been made pursuant to
|
||||
Section 4(a), keep intact all copyright notices for the Work and
|
||||
provide, reasonable to the medium or means You are utilizing: (i) the
|
||||
name of the Original Author (or pseudonym, if applicable) if supplied,
|
||||
and/or if the Original Author and/or Licensor designate another party
|
||||
or parties (e.g., a sponsor institute, publishing entity, journal) for
|
||||
attribution ("Attribution Parties") in Licensor's copyright notice,
|
||||
terms of service or by other reasonable means, the name of such party
|
||||
or parties; (ii) the title of the Work if supplied; (iii) to the
|
||||
extent reasonably practicable, the URI, if any, that Licensor
|
||||
specifies to be associated with the Work, unless such URI does not
|
||||
refer to the copyright notice or licensing information for the Work;
|
||||
and, (iv) consistent with Section 3(b), in the case of an Adaptation,
|
||||
a credit identifying the use of the Work in the Adaptation (e.g.,
|
||||
"French translation of the Work by Original Author," or "Screenplay
|
||||
based on original Work by Original Author"). The credit required by
|
||||
this Section 4(c) may be implemented in any reasonable manner;
|
||||
provided, however, that in the case of a Adaptation or Collection, at
|
||||
a minimum such credit will appear, if a credit for all contributing
|
||||
authors of the Adaptation or Collection appears, then as part of these
|
||||
credits and in a manner at least as prominent as the credits for the
|
||||
other contributing authors. For the avoidance of doubt, You may only
|
||||
use the credit required by this Section for the purpose of attribution
|
||||
in the manner set out above and, by exercising Your rights under this
|
||||
License, You may not implicitly or explicitly assert or imply any
|
||||
connection with, sponsorship or endorsement by the Original Author,
|
||||
Licensor and/or Attribution Parties, as appropriate, of You or Your
|
||||
use of the Work, without the separate, express prior written
|
||||
permission of the Original Author, Licensor and/or Attribution
|
||||
Parties.
|
||||
d. For the avoidance of doubt:
|
||||
|
||||
i. Non-waivable Compulsory License Schemes. In those jurisdictions in
|
||||
which the right to collect royalties through any statutory or
|
||||
compulsory licensing scheme cannot be waived, the Licensor
|
||||
reserves the exclusive right to collect such royalties for any
|
||||
exercise by You of the rights granted under this License;
|
||||
ii. Waivable Compulsory License Schemes. In those jurisdictions in
|
||||
which the right to collect royalties through any statutory or
|
||||
compulsory licensing scheme can be waived, the Licensor reserves
|
||||
the exclusive right to collect such royalties for any exercise by
|
||||
You of the rights granted under this License if Your exercise of
|
||||
such rights is for a purpose or use which is otherwise than
|
||||
noncommercial as permitted under Section 4(b) and otherwise waives
|
||||
the right to collect royalties through any statutory or compulsory
|
||||
licensing scheme; and,
|
||||
iii. Voluntary License Schemes. The Licensor reserves the right to
|
||||
collect royalties, whether individually or, in the event that the
|
||||
Licensor is a member of a collecting society that administers
|
||||
voluntary licensing schemes, via that society, from any exercise
|
||||
by You of the rights granted under this License that is for a
|
||||
purpose or use which is otherwise than noncommercial as permitted
|
||||
under Section 4(c).
|
||||
e. Except as otherwise agreed in writing by the Licensor or as may be
|
||||
otherwise permitted by applicable law, if You Reproduce, Distribute or
|
||||
Publicly Perform the Work either by itself or as part of any
|
||||
Adaptations or Collections, You must not distort, mutilate, modify or
|
||||
take other derogatory action in relation to the Work which would be
|
||||
prejudicial to the Original Author's honor or reputation. Licensor
|
||||
agrees that in those jurisdictions (e.g. Japan), in which any exercise
|
||||
of the right granted in Section 3(b) of this License (the right to
|
||||
make Adaptations) would be deemed to be a distortion, mutilation,
|
||||
modification or other derogatory action prejudicial to the Original
|
||||
Author's honor and reputation, the Licensor will waive or not assert,
|
||||
as appropriate, this Section, to the fullest extent permitted by the
|
||||
applicable national law, to enable You to reasonably exercise Your
|
||||
right under Section 3(b) of this License (right to make Adaptations)
|
||||
but not otherwise.
|
||||
|
||||
5. Representations, Warranties and Disclaimer
|
||||
|
||||
UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
|
||||
OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
|
||||
KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
|
||||
INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
|
||||
FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
|
||||
LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
|
||||
WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION
|
||||
OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
|
||||
|
||||
6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
|
||||
LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR
|
||||
ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES
|
||||
ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS
|
||||
BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
|
||||
|
||||
7. Termination
|
||||
|
||||
a. This License and the rights granted hereunder will terminate
|
||||
automatically upon any breach by You of the terms of this License.
|
||||
Individuals or entities who have received Adaptations or Collections
|
||||
from You under this License, however, will not have their licenses
|
||||
terminated provided such individuals or entities remain in full
|
||||
compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will
|
||||
survive any termination of this License.
|
||||
b. Subject to the above terms and conditions, the license granted here is
|
||||
perpetual (for the duration of the applicable copyright in the Work).
|
||||
Notwithstanding the above, Licensor reserves the right to release the
|
||||
Work under different license terms or to stop distributing the Work at
|
||||
any time; provided, however that any such election will not serve to
|
||||
withdraw this License (or any other license that has been, or is
|
||||
required to be, granted under the terms of this License), and this
|
||||
License will continue in full force and effect unless terminated as
|
||||
stated above.
|
||||
|
||||
8. Miscellaneous
|
||||
|
||||
a. Each time You Distribute or Publicly Perform the Work or a Collection,
|
||||
the Licensor offers to the recipient a license to the Work on the same
|
||||
terms and conditions as the license granted to You under this License.
|
||||
b. Each time You Distribute or Publicly Perform an Adaptation, Licensor
|
||||
offers to the recipient a license to the original Work on the same
|
||||
terms and conditions as the license granted to You under this License.
|
||||
c. If any provision of this License is invalid or unenforceable under
|
||||
applicable law, it shall not affect the validity or enforceability of
|
||||
the remainder of the terms of this License, and without further action
|
||||
by the parties to this agreement, such provision shall be reformed to
|
||||
the minimum extent necessary to make such provision valid and
|
||||
enforceable.
|
||||
d. No term or provision of this License shall be deemed waived and no
|
||||
breach consented to unless such waiver or consent shall be in writing
|
||||
and signed by the party to be charged with such waiver or consent.
|
||||
e. This License constitutes the entire agreement between the parties with
|
||||
respect to the Work licensed here. There are no understandings,
|
||||
agreements or representations with respect to the Work not specified
|
||||
here. Licensor shall not be bound by any additional provisions that
|
||||
may appear in any communication from You. This License may not be
|
||||
modified without the mutual written agreement of the Licensor and You.
|
||||
f. The rights granted under, and the subject matter referenced, in this
|
||||
License were drafted utilizing the terminology of the Berne Convention
|
||||
for the Protection of Literary and Artistic Works (as amended on
|
||||
September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
|
||||
Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996
|
||||
and the Universal Copyright Convention (as revised on July 24, 1971).
|
||||
These rights and subject matter take effect in the relevant
|
||||
jurisdiction in which the License terms are sought to be enforced
|
||||
according to the corresponding provisions of the implementation of
|
||||
those treaty provisions in the applicable national law. If the
|
||||
standard suite of rights granted under applicable copyright law
|
||||
includes additional rights not granted under this License, such
|
||||
additional rights are deemed to be included in the License; this
|
||||
License is not intended to restrict the license of any rights under
|
||||
applicable law.

*
|
||||
* gif.h by Charlie Tangora [ctangora -at- gmail -dot- com]
|
||||
* adapted to C99 and reformatted by Ramon Santamaria (@raysan5)
|
||||
*
|
||||
* This file offers a simple, very limited way to create animated GIFs directly in code.
|
||||
*
|
||||
* Those looking for particular cleverness are likely to be disappointed; it's pretty
|
||||
* much a straight-ahead implementation of the GIF format with optional Floyd-Steinberg
|
||||
* dithering. (It does at least use delta encoding - only the changed portions of each
|
||||
* frame are saved.)
|
||||
*
|
||||
* So resulting files are often quite large. The hope is that it will be handy nonetheless
|
||||
* as a quick and easily-integrated way for programs to spit out animations.
|
||||
*
|
||||
* Only RGBA8 is currently supported as an input format. (The alpha is ignored.)
|
||||
*
|
||||
* CONFIGURATION:
|
||||
*
|
||||
* #define GIF_IMPLEMENTATION
|
||||
* Generates the implementation of the library into the included file.
|
||||
* If not defined, the library is in header only mode and can be included in other headers
|
||||
* or source files without problems. But only ONE file should hold the implementation.
|
||||
*
|
||||
* USAGE:
|
||||
* 1) Create a GifWriter struct. Pass it to GifBegin() to initialize and write the header.
|
||||
* 2) Pass subsequent frames to GifWriteFrame().
|
||||
* 3) Finally, call GifEnd() to close the file handle and free memory.
