<text>Particles are lightweight objects which are not synchronized in a network game. This means that on the one hand you can create huge amounts of particles without slowing down the game too much but on the other hand there are only limited options for control of particle behaviour. If the particles are not sufficient for a given effect you have in mind, you can always use true objects instead.</text>

<text>If a particle is defined in a ocd group, any object definition located in the same group is ignored. This used to be a way to allow loading of placeholder options in the old graphics system which didn't support particles.</text>

</text>
|
||||
<h id="attributes">Properties</h>
|
||||
<text>Each particle has a position (x, y), horizontal and vertical impulse (xdir and ydir), life time (life), and two extra parameters (a and b). These are initialized by script and then processed by the <a href="#funcs">particle functions</a>. For more information see <a href="#funcs">particle functions</a> and <a href="#drawfuncs">drawing functions</a>.</text>
|
||||
<h id="face">Graphics</h>
|
||||
<text>The coordinates for the source rectangle within Graphics.png of a particle are comparable to the Face entry in an object's <emlink href="definition/actmap.html">ActMap</emlink>. The coordinates only specify the first animation phase. All following animation phases should be located on the right (with smoke also below) of the initial phase. The animation length is then automatically determined from the image size. For the drawing offset you should usually specify half the particle size. An offset 0/0 would cause the particle graphics to be drawn below actual particle position.</text>
|
||||
<text>If Delay = 0, a random animation phase is chosen on startup and maintained. The particle will exist until is falls out of the landscape.</text>
|
||||
<h id="maxcount">Particle Amounts</h>
|
||||
<text>For each particle type a maximum count is defined which is then also adjusted by the configuration setting for effect levels in the graphics options. As soon as half of the maximum amount of particles is created, new particles are only created based on random selected and the closer you get to the maximum value, the smaller the chance of new particle generation. This ensures a smooth approach to the actual limit.</text>
|
||||
<h id="collision">Collision Detection</h>
|
||||
<text>Particles can collide with the landscape. This is not very exact, however. Fast moving particles might pass through very thin layers of solid materials. If you need more precision, you should use objects instead.</text>
|
||||
<text>Collision detection is only done in StdExec (i.e. not with smoke particles). For valid functions see <a href="#funcs">particle functions</a>. Collision detection is done at the particle center and only if VertexCount is specified. The point of detection can be shifted using VertexY. The specified values are in percent of the particle size, meaning VertexY=100 would check at the bottom of the particle. The visual size specified in Face doesn't affect this.</text>
|
||||
<h id="funcs">Particle Functions</h>
|
||||
<text>The behaviour of particles can be controlled by predefined particle functions. These are executed for initialization, then at each fram, and in case of <a href="#collision">collision</a> with the landscape.</text>
|
||||
<dl>
|
||||
<dt id="stdexec">StdExec</dt>
|
||||
<dd>
|
||||
<text>Standard function ExecFn for almost all particle types. The particle runs through an animation defined by Face, Delay, Repeats, Reverse, FadeOutLen, and FadeOutDelay and is then destroyed. The extra parameter defines the size of the particle in 1/10 pixels. b defines color modulation; if b = 0 no modulation is applied. aa as well as b are not modified by this function and will preserve the <a href="#control">initial</a> values. Also, the particle moves according to xdir and ydir while ydir is affected by gravity if GravityAcc is enabled.</text>

</text>
|
||||
<h id="attributes">Properties</h>
|
||||
<text>Each particle has a position (x, y), horizontal and vertical impulse (xdir and ydir), life time (life), and two extra parameters (a and b). These are initialized by script and then processed by the <a href="#funcs">particle functions</a>. For more information see <a href="#funcs">particle functions</a> and <a href="#drawfuncs">drawing functions</a>.</text>
|
||||
<h id="face">Graphics</h>
|
||||
<text>The coordinates for the source rectangle within Graphics.png of a particle are comparable to the Face entry in an object's <emlink href="definition/actmap.html">ActMap</emlink>. The coordinates only specify the first animation phase. All following animation phases should be located on the right (with smoke also below) of the initial phase. The animation length is then automatically determined from the image size. For the drawing offset you should usually specify half the particle size. An offset 0/0 would cause the particle graphics to be drawn below actual particle position.</text>
|
||||
<text>If Delay = 0, a random animation phase is chosen on startup and maintained. The particle will exist until is falls out of the landscape.</text>
|
||||
<h id="maxcount">Particle Amounts</h>
|
||||
<text>For each particle type a maximum count is defined which is then also adjusted by the configuration setting for effect levels in the graphics options. As soon as half of the maximum amount of particles is created, new particles are only created based on random selected and the closer you get to the maximum value, the smaller the chance of new particle generation. This ensures a smooth approach to the actual limit.</text>
|
||||
<h id="collision">Collision Detection</h>
|
||||
<text>Particles can collide with the landscape. This is not very exact, however. Fast moving particles might pass through very thin layers of solid materials. If you need more precision, you should use objects instead.</text>
|
||||
<text>Collision detection is only done in StdExec (i.e. not with smoke particles). For valid functions see <a href="#funcs">particle functions</a>. Collision detection is done at the particle center and only if VertexCount is specified. The point of detection can be shifted using VertexY. The specified values are in percent of the particle size, meaning VertexY=100 would check at the bottom of the particle. The visual size specified in Face doesn't affect this.</text>
|
||||
<h id="funcs">Particle Functions</h>
|
||||
<text>The behaviour of particles can be controlled by predefined particle functions. These are executed for initialization, then at each fram, and in case of <a href="#collision">collision</a> with the landscape.</text>
|
||||
<dl>
|
||||
<dt id="stdexec">StdExec</dt>
|
||||
<dd>
|
||||
<text>Standard function ExecFn for almost all particle types. The particle runs through an animation defined by Face, Delay, Repeats, Reverse, FadeOutLen, and FadeOutDelay and is then destroyed. The extra parameter defines the size of the particle in 1/10 pixels. b defines color modulation; if b = 0 no modulation is applied. aa as well as b are not modified by this function and will preserve the <a href="#control">initial</a> values. Also, the particle moves according to xdir and ydir while ydir is affected by gravity if GravityAcc is enabled.</text>

<desc>The value will be a random number in the interval from start_value to (not including) end_value. The values in between are not whole integers, but are also in fraction of integers. This means that PV_Random(0, 1) can not only return one value (the 0) but a lot of different values in the interval between 0 and 1.</desc>
