Heatcloud
Contents |
[edit] Introduction
heatcloud is one of the simplest and most common explosion types. Ironically, it is also one of the least intuitive. First of all, ignore the name--it basically makes an expanding image at the point at which it is spawned.

[edit] Suggested Use
heatcloud makes a good main piece of an explosion. Think of it as a background for the other components of your explosion generator.
[edit] Parameters
[edit] heat, maxheat, heatFalloff
Most explosions have alpha and ttl. I don't know why heatcloud uses these instead. Basically:
Starting alpha = heat / maxheat
ttl = heat / heatFalloff
The alpha decreases linearly across the heatcloud's lifetime.
[edit] size, sizeGrowth
The heatcloud starts at size size and grows sizeGrowth each frame.
[edit] sizemod, sizemodmod
It seems that the heatcloud expands by a factor of (1 - sizemod) each frame. The sizemod itself is multiplied by sizemodmod every frame. Most of the time it's probably best just not to contemplate these.
[edit] texture
The texture of the heatcloud.
