draw_point3d

draw_point3d(VECTOR* pos, COLOR* color, var alpha, var size)

Writes a point - a colored square - at a given position in the level, mostly for testing / debugging purposes.

Parameters:

pos	XYZ position in the level
color	BGR color vector that determines the point color
alpha	Transparency, from 0 (full transparent) to 100 (opaque)
size	Point size in quants

Remarks:

The point is only visible during the next frame. For displaying it permanently, use a while ... wait(1) loop.
Every point is using a particle, so adjust max_particles if you need many points.
For drawing a 2D point at a xy position on the screen, use draw_quad.

Speed:

Fast

Example:

// display all vertices on a model mesh
action show_my_vertices()
{
  var i;
  while(1) {
    i = ent_vertices(my);
    var pos[3];
    while (i > 0) {
      draw_point3d(vec_for_vertex(pos,my,i),COLOR_RED,100,5);
      i -= 1;
    }
	  wait(1);
  }
}
