add a particle at an absolute world position (not relative to psys->source)

Parameters:

  • psys targeted particle system
  • spr sprite id (-1 for none)
  • mode particle draw mode
  • px absolute x position
  • py absolute y position
  • pz absolute z position
  • lifetime duration in msecs
  • size_start particle size at birth
  • size_end particle size at death
  • color_start particle start color
  • color_end particle end color (lerped over lifetime)
  • vx x velocity
  • vy y velocity
  • vz z velocity
  • ax x acceleration
  • ay y acceleration
  • az z acceleration

Return: TRUE or FALSE

function add_particle

int add_particle(
    PARTICLE_SYSTEM * psys,
    int spr,
    int mode,
    int lifetime,
    int size,
    ALLEGRO_COLOR color,
    PHYSICS object
)

add a particle to the system

Parameters:

  • psys targeted particle system
  • spr sprite id of the particle, if any. Set to negative if there is no sprite for the particle
  • mode particle mode, NORMAL_PART:if sprite id then use sprite, else draw a pixel,SINUS_PART: snow moving effect,PIXEL_PART: rectfill with size
  • lifetime duration of the particle in msecs
  • size size of the particle, in pixels
  • color color of the particle
  • object PHYSICS object in which you set the particle initial position, speed, acceleration, rotation

Return: TRUE or FALSE

Parameters:

  • psys the targeted particle system

Return: pointer to the new emitter for caller to configure, or NULL on error

add a new emitter to the particle system

Returns pointer for caller to configure, or NULL on error.
