Position_free

Description

Checks if there are no instances of a solid object that collide with the given position and returns the result.

Parameters

Parameter	Data Type	Description
x	cs_scalar	x coordinate of the position
y	cs_scalar	y coordinate of the position

Return Values

boolean: Returns whether no instances of a solid object collide with the position.

Example Call

// demonstrates checking if there is an instance of a solid object at the next position before moving
var mx, my;
mx = x + lengthdir_x(speed, direction);
my = y + lengthdir_y(speed, direction);
if (position_free(mx, my)) {
  x = mx;
  y = my;
} else {
  // there is an instance of a solid object at the next position so we can't move
}
