particle.cfg

The particle.cfg file stores particle configuration data and settings for the particle system of Vice City and GTA III.

Format

All information is stored in plain-text format as a simple list of settings. Each line defines one entry. Lines can also be commented. Unlike the data files the typical comment character for configuration files is the semicolon (;). Each line is a collection of values seperated by tabstops. The following table shows the values and their description in the order they appear inside the file:

Value	Type	Description
Particle name	String	The name of the particle for the script.
Rendering color	Color (RGB)	3 values (from 0 to 255) defining the red, green and blue level of the particle color.
Initial color variation	Integer	Value between 0 and 100, defining the initial color variation of the particle. Using this value a random value gets calculated to manipulate each color level of the particle. This makes every particle look different. Example: Rendering color = (100, 100, 100), Initial color variation = 20 Real variation = random(-20, 20) Real color = (100 + Real variation, 100 + Real variation, 100 + Real variation)
Fade destination color	Color (RGB)	3 values (from 0 to 255) defining the red, green and blue level of the destination color if the particle is fading.
Fading time	Integer	Value between 0 and 100, defining the time required to fade from the rendering color to the fade destination color.
Initial radius	Float	The initial radius of the particle sprite.r.
Expansion rate	Float	The rate the particle sprite grows during it's lifetime.
Fade to black initial intensity	Integer	If the particle "fades to black" (means it get's destroyed with fading) this value defines it's initial intensity. The value can be between 0 and 255 where 255 means 100%.
Fade to black time	Integer	The number of frames between each fade step.
Fade to black amount	Integer	The amount the initial intensity gets decreased with each step.
Initial rotation	Integer	The initial angle around the z-axis. This value must can be between 0 and 1023.
Rotation change time	Integer	The number of frames between each rotation step.
Rotation change amount	Integer	The amount the sprite gets rotated around the z-axis with each step.
Initial radius	Float	The initial radius of the particle around the z-axis.
Radius change time	Integer	The number of frames between each radius change step.
Radius change amount	Float	The amount the radius changes with each step.
Animation speed	Integer	The time between each animation step. 0 means that the particle is not animated.
Animation start frame	Integer	The index first frame of the animated particle.
Animation final frame	Integer	The index of the last frame of the animated particle.
Gravitational accleration	Float	The accleration of the particle falling to the ground.
Frictional deccleration	Float	The frictional deccleration of the particle. This value can be between 0 and 1 where 1 represents 100%.
Default lifetime	Integer	The default lifetime of the particle in milliseconds.
Position error	Float	The final position gets corrected using a random value between 0 and this one.
Velocity error	Float	The final velocity gets corrected using a random value between 0 and this one.
Expansion error	Float	The expansion rate gets corrected using a random value between 0 and this one.
Rotation error	Float	The rotation rate gets corrected using a random value between 0 and this one.
Lifetime error	Integer	Value between 0 and 255 defining the shape for the distribution of the particles lifetime.
Trail length error	Float	If the particle trail flag is set the length of it's trail gets multiplied by this value.
Strech X	Float	The amount the particles texture gets streched along x-axis.
Strech Y	Float	The amount the particles texture gets streched along y-axis.
Wind influence	Float	The factor for the influence of wind for the particle.
Creation range	Float	The maximum distance from the camera for actually creating the particle.
Flags	Integer	See below!

Flags

There are different flags that influence the particles rendering process. Those flags are listed in the following table:

Name	Flag	Binary	Description
–	-1	1111 1111 1111 1111	Enables all flags. [1] Never used by default.
