<h1>Dynamic Bindings<a class="headerlink" href="#dynamic-bindings" title="Permalink to this heading"></a></h1>
|
||
<p>CFFI ABI dynamic bindings avoid the need to compile a C extension module. They now been moved to a separate module:</p>
|
||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">python3</span> <span class="o">-</span><span class="n">m</span> <span class="n">pip</span> <span class="n">install</span> <span class="n">raylib_dynamic</span>
|
||
</pre></div>
|
||
</div>
|
||
<div class="admonition warning">
|
||
<p class="admonition-title">Warning</p>
|
||
<p>There have been some weird failures with dynamic bindings and ctypes bindings before and often the
|
||
failures are silent
|
||
so you don’t even know something has gone wrong and you don’t get proper stacktraces. Also the static bindings are faster.
|
||
Therefore I personally recommend the static ones.
|
||
But the dynamic bindings have the advantage that you don’t need to compile anything to install. You just need a Raylib DLL.</p>
|
||
</div>
|
||
<p>The API is exactly the same as the static one documented here. (Therefore you can’t have both modules installed at once.) The only difference is you can’t do:</p>
|
||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="kn">from</span> <span class="nn">raylib</span> <span class="kn">import</span> <span class="o">*</span>
|
||
</pre></div>
|
||
</div>
|
||
<p>Instead you have to do:</p>
|
||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="kn">from</span> <span class="nn">raylib</span> <span class="kn">import</span> <span class="n">rl</span>
|
||
</pre></div>
|
||
</div>
|
||
<p>Then you access the functions with <code class="docutils literal notranslate"><span class="pre">rl.</span></code> prefix.</p>
|
||
<p>See <a class="reference external" href="https://github.com/electronstudio/raylib-python-cffi/blob/master/dynamic/test_dynamic.py">https://github.com/electronstudio/raylib-python-cffi/blob/master/dynamic/test_dynamic.py</a> for an example.</p>
|
||
<p>If you use the <code class="docutils literal notranslate"><span class="pre">rl.</span></code> prefix then code will work on both static and dynamic bindings.</p>
|
||
<div class="admonition tip">
|
||
<p class="admonition-title">Tip</p>
|
||
<p>If you access functions via <code class="docutils literal notranslate"><span class="pre">import</span> <span class="pre">pyray</span></code> then there is no difference at all, but be warned this hasn’t been tested much.</p>
|
||
</div>
|
||
<div class="admonition note">
|
||
<p class="admonition-title">Note</p>
|
||
<p>Standard Raylib DLLs do not include additional libraries like Raygui, Physac, etc. So these functions won’t work.</p>
|
||
</div>
|
||
<div class="admonition important">
|
||
<p class="admonition-title">Important</p>
|
||
<p>If your system already has the Raylib library installed, you can set the environment variable <code class="docutils literal notranslate"><span class="pre">USE_EXTERNAL_RAYLIB</span></code> and it will
|
||
always be used instead of the bundled DLLs.</p>
