gravity_direction;
Returns: Real
All instances in GameMaker: Studio have certain "built
in" properties that you can use and set to govern how they look and
behave. Gravity_direction is one of those properties and
can be used to set the direction of movement when the instances
gravity is greater than 0. Note
that directions in GameMaker: Studio are usually calculated
as 0° being right, 90° being up, 180° being left and 270° being
down.
if place_meeting(x, y, obj_switch)
{
gravity_direction += 180;
}
The above code will change the gravity_direction if the player object meets an instance of "obj_switch".
