<h1>4 Color Keywords</h1>
|
|
|
|
<h2><a name = "alpha">4.1 alpha <value></a></h2>
|
|
<p><pre class = "type">
|
|
Specifies the initial alpha value of the effect
|
|
</pre>
|
|
|
|
<h2><a name = "alpharand">4.2 alpharand <value></a></h2>
|
|
<p><pre class = "type">
|
|
Specifies a randomized additonal value added to each particle's initial alpha.
|
|
</pre>
|
|
|
|
<h2><a name = "alphadelta">4.3 alphadelta <value></a></h2>
|
|
<p><pre class = "type">
|
|
Specifies how much the alpha value of the effect changes per second (subtracted)
|
|
</pre>
|
|
|
|
<h2><a name = "rgbdeltatime">4.4 rgbdeltatime <value></a></h2>
|
|
<p><pre class = "type">
|
|
Specifies for how long the particle may change colours for.
|
|
After this many seconds, the particle may no longer change colours (delta becomes 0).
|
|
</pre>
|
|
|
|
<h2><a name = "rampmode">4.5 rampmode <mode></a></h2>
|
|
<p><pre class = "type">
|
|
Mode may be one of:
|
|
none: uses rgb+rand+sync+delta+scale+scaledelta values.
|
|
nearest(or absolute): the ramp overrides all colour+scale values. The effect moves from one absolute ramp index to the next.
|
|
lerp: smoothly interpolates from one value to the next.
|
|
delta: uses rgb+rand+sync+scale, but not delta values. All delta values come from the colour ramp instead.
|
|
|
|
If not none, the ramp index used is based upon the particle's age, its lifetime, and how many ramp elements there are.
|
|
</pre>
|
|
|
|
<h2><a name = "rampindexlist">4.6 rampindexlist <idx1> [<idx2> [idx3 ...]]</a></h2>
|
|
<p><pre class = "type">
|
|
Scale used is the currently set scale value.
|
|
Specifies a set of palette index values to use for the effect as part of the effect's colour ramp.
|
|
</pre>
|
|
|
|
<h2><a name = "rampindex">4.7 rampindex <idx> <scale></a></h2>
|
|
<p><pre class = "type">
|
|
Specifies an individual palette index value and particle scale to use for the effect as part of the effect's colour ramp
|
|
</pre>
|
|
|
|
<h2><a name = "ramp">4.8 ramp <red> <green> <blue> [alpha] [scale]</a></h2>
|
|
<p><pre class = "type">
|
|
Specifies a ramp index in rgb terms, regardless of palette.
|
|
</pre>
|
|
|
|
<h2><a name = "blend">4.9 blend <mode></a></h2>
|
|
<p><pre class = "type">
|
|
If the texture used is actually a material then that material's blend mode will take precidence.
|
|
As a general rule you should try to use only the premul blend modes (as well as atlasing).
|
|
|
|
Mode may be one of:
|
|
adda:
|
|
addc:
|
|
subtract:
|
|
invmoda:
|
|
invmodc:
|
|
blendcolour:
|
|
blendalpha:
|
|
premul_subtract:
|
|
premul_add:
|
|
premul_blend:
|
|
rtsmoke:
|
|
</pre>
|
|
|
|
<h2><a name = "stains">4.10 stains <value></a></h2>
|
|
<p><pre class = "type">
|
|
How much the effect discolours the wall upon impact.
|
|
The stained colour is based upon the colour of the particle upon impact.
|
|
</pre>
|
|
|
|
<h2><a name = "spawnstain">4.11 spawnstain <radius> <r> <g> <b></a></h2>
|
|
<p><pre class = "type">
|
|
Controls whether a stain will be created at the same time as any particles
|
|
(instead of depending upon impacts).
|
|
</pre>
