angle
Definition
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.
Example
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
Used in example: map_new()
, map_clear()
, rgb()
, map_unload()
, key()
, exit_status, graph
, x, y, angle
This process will spin the cyan square by 1 degree each frame.
