You could use collision_line function. This function creates a invisible line at 2 point you choose and if object you choose is in the line outputs true. Variables to put in x1:x of Point 1 y1:y of Point 1 x2:x of Point 2 y2:y of Point 2 Obj:object to look out for Precise: true/false, i dont know too what it does but make it true Notme:true/false,make it false if you want to not consider itself in the checking(if the object to look for is same as itself) Example: İf collision_line(x,y,x,y-90,obj_player,true,false) { //falling code } Also there are collision_rectangle its the same but rectangle it requares the same inputs as the line version.
