INT angle = 0
Angle is a predefined local variable which holds the angle (measured in 1/1000 of a degree) at which the graphic of that process (assigned by the local variable graph) will be drawn. It also influences the result of the function advance().
An angle of 0 means to the right, 90000 means up, 180000 means left and 270000 and -90000 mean down.
To make the graphic of a process spin:
import "mod_grproc" import "mod_map" import "mod_wm" // for exit_status import "mod_key" // for key() Process Main() Begin graph = map_new(100,100,8); //Create a cyan square and assign it to 'graph' map_clear(0,graph,rgb(0,255,255)); x = 160; //Position the graphic's center y = 100; //in the center of the screen Repeat angle += 1000; //increase the angle of graphic by 1000 each frame. 1000 = 1 degree. frame; Until(key(_ESC) || exit_status) OnExit map_unload(0,graph); End
This process will spin the cyan square by 1 degree each frame.
