hgeParticleSystemInfo *<i><b>psi</b></i>,
float <i><b>x</b></i>,
float <i><b>y</b></i>
);
</pre>
<h2>Parameters</h2>

<dt><i>psi</i>
<dd>Pointer to a valid <a href="hgeparticle_psinfo.html">hgeParticleSystemInfo</a> structure, describing the particle system.

<h2>Return value</h2>
<p>
If succeeded returns pointer to the created particle system,

</p>
<h2>Remarks</h2>
<p>
The maximum number of simultaneously allowed particle systems within one manager is 100.
If you try to create more particle systems, <b>SpawnPS</b> will return 0.
<br><br>
The manager monitors a particle system created by <b>SpawnPS</b> method and
removes it from memory as soon as it is stopped (either manually or
because of it's life time have passed) and all it's particles are dead.
<br><br>
If you want to access the particle system via the pointer returned by <b>SpawnPS</b>,
you should first ensure that the pointer is valid with <a href="hgepmanager_ispsalive.html">IsPSAlive</a> method.
Also, don't delete the returned pointer manually, this may cause system crash.
