<h3>Main</h3>
<div class="level3">

<p>
The following functions are the main hps functions that the HPL2 engine looks to run on certain events - similar to the C++ int main() function.
</p>
<pre class="code c++"><span class="kw4">void</span> OnStart<span class="br0">(</span><span class="br0">)</span><span class="br0">{</span> <span class="br0">}</span>



</pre><p> </p>




<p>
The function that runs when the map is loaded for the first time.
</p>
<pre class="code c++"><span class="kw4">void</span> OnEnter<span class="br0">(</span><span class="br0">)</span><span class="br0">{</span> <span class="br0">}</span>



</pre><p> </p>




<p>
The function that runs whenever the player enters a map.
</p>
<pre class="code c++"><span class="kw4">void</span> OnLeave<span class="br0">(</span><span class="br0">)</span><span class="br0">{</span> <span class="br0">}</span>



</pre><p> </p>




<p>
The function that runs when the player leaves a map.
</p>
<pre class="code c++"><span class="kw4">void</span> OnGameStart<span class="br0">(</span><span class="br0">)</span><span class="br0">{</span> <span class="br0">}</span>



</pre><p> </p>




<p>
This function is found in the global.hps file and the inventory.hps file, and is run when the game is first started by the player (ie via "Start New Game").

<p>
These functions push objects. Note that rather high values are needed when applying <em>forces</em> (on the order of ~100 (weak) to ~10000 (strong)), but not impulses (values less than 10 can be appropriate). Forces are external influences, and will have different effect depending on the mass of the object they are being applied to; impulses disregard mass, and can cause objects to break, as if hit.  A "Body" is a physics-related helper object, to which a force or an impulse can be applied. Entities can consist of several bodies, interconnected in various ways (you can create/examine bodies in the model editor).
</p>

<p>
<em>asName </em>- the object to push; for bodies, use this format: "<em>entityName</em>_<em>bodyName</em>"<br/>

<em>afX </em>- magnitude along the X-axis<br/>

<em>afY </em>- magnitude along the Y-axis<br/>

<em>afZ </em>- magnitude along the Z-axis<br/>

<em>asCoordSystem </em>- determines which coordinate system is used, usually "world"  All of these functions are <em>additive</em> - when called consecutively, for each call, the vectors defined by (afX, afY, afZ) will be added together, and a resultant force/impulse will be calculated <em>before</em> any physics simulation is applied to the target object.
