Jest to przydatna funkcjonalność przy tworzeniu gier lub ogólnie aplikacji wykorzystującej fizykę. Z ich pomocą można zaimplementować szereg mechanik, jak zadanie obrażeń w wyniku trafienia pociskiem/bronią białą, wywołanie animacji czy przytwierdzenie haka do ściany. </span></p><p><span>Implementacja wymaga najpierw zdefiniowania swojego </span><em><span>filter shadera</span></em><span>, w którym należy zdefiniować jak mają być obsłużone zdarzenia w scenie physx. W poniższej definicji definiujemy, że punkty zderzenia będą obsługiwane przez </span><code>OnContact</code><span>.</span></p><pre lang="C++" spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded"><div class="CodeMirror cm-s-inner cm-s-null-scroll CodeMirror-wrap" lang="c++"><div style="overflow: hidden; position: relative; width: 3px; height: 0px; top: 9.5px; left: 8px;"><textarea autocorrect="off" autocapitalize="off" spellcheck="false" tabindex="0" style="position: absolute; bottom: -1em; padding: 0px; width: 1000px; height: 1em; outline: none;"></textarea></div><div class="CodeMirror-scrollbar-filler" cm-not-content="true"></div><div class="CodeMirror-gutter-filler" cm-not-content="true"></div><div class="CodeMirror-scroll" tabindex="-1"><div class="CodeMirror-sizer" style="margin-left: 0px; margin-bottom: 0px; border-right-width: 0px; padding-right: 0px; padding-bottom: 0px;"><div style="position: relative; top: 0px;"><div class="CodeMirror-lines" role="presentation"><div role="presentation" style="position: relative; outline: none;"><div class="CodeMirror-measure"><pre><span>xxxxxxxxxx</span></pre></div><div class="CodeMirror-measure"></div><div style="position: relative; z-index: 1;"></div><div class="CodeMirror-code" role="presentation" style=""><div class="CodeMirror-activeline" style="position: relative;"><div class="CodeMirror-activeline-background CodeMirror-linebackground"></div><div class="CodeMirror-gutter-background CodeMirror-activeline-gutter" style="left: 0px; width: 0px;"></div><pre class=" CodeMirror-line " role="presentation"><span role="presentation" style="padding-right: 0.1px;"><span class="cm-keyword">static</span> <span class="cm-variable">PxFilterFlags</span> <span class="cm-def">simulationFilterShader</span>(<span class="cm-variable">PxFilterObjectAttributes</span> <span class="cm-variable">attributes0</span>,</span></pre></div><pre class=" CodeMirror-line " role="presentation"><span role="presentation" style="padding-right: 0.1px;"> <span class="cm-variable">PxFilterData</span> <span class="cm-variable">filterData0</span>, <span class="cm-variable">PxFilterObjectAttributes</span> <span class="cm-variable">attributes1</span>, <span class="cm-variable">PxFilterData</span> <span class="cm-variable">filterData1</span>,</span></pre><pre class=" CodeMirror-line " role="presentation"><span role="presentation" style="padding-right: 0.1px;"> <span class="cm-variable">PxPairFlags</span><span class="cm-operator">&</span> <span class="cm-variable">pairFlags</span>, <span class="cm-keyword">const</span> <span class="cm-variable-3">void*</span> <span class="cm-variable">constantBlock</span>, <span class="cm-variable">PxU32</span> <span class="cm-variable">constantBlockSize</span>)</span></pre><pre class=" CodeMirror-line " role="presentation"><span role="presentation" style="padding-right: 0.1px;">{</span></pre><pre class=" CodeMirror-line " role="presentation"><span role="presentation" style="padding-right: 0.1px;"> <span class="cm-variable">pairFlags</span> <span class="cm-operator">=</span></span></pre><pre class=" CodeMirror-line " role="presentation"><span role="presentation" style="padding-right: 0.1px;"> <span class="cm-variable">PxPairFlag::eCONTACT_DEFAULT</span> <span class="cm-operator">|</span> <span class="cm-comment">// default contact processing</span></span></pre><pre class=" CodeMirror-line " role="presentation"><span role="presentation" style="padding-right: 0.1px;"> <span class="cm-variable">PxPairFlag::eNOTIFY_CONTACT_POINTS</span> <span class="cm-operator">|</span> <span class="cm-comment">// contact points will be available in onContact callback</span></span></pre><pre class=" CodeMirror-line " role="presentation"><span role="presentation" style="padding-right: 0.1px;"> <span class="cm-variable">PxPairFlag::eNOTIFY_TOUCH_FOUND</span>; <span class="cm-comment">// onContact callback will be called for this pair</span></span></pre><pre class=" CodeMirror-line " role="presentation"><span role="presentation" style="padding-right: 0.1px;"> </span></pre><pre class=" CodeMirror-line " role="presentation"><span role="presentation" style="padding-right: 0.1px;"> <span class="cm-keyword">return</span> <span class="cm-variable">physx::PxFilterFlag::eDEFAULT</span>;</span></pre><pre class=" CodeMirror-line " role="presentation"><span role="presentation" style="padding-right: 0.1px;">}</span></pre><div class="" style="position: relative;"><pre class=" CodeMirror-line " role="presentation"><span role="presentation" style="padding-right: 0.1px;"><span cm-text="" cm-zwsp="">
