Title: Returning objects, solids, and Game Maker.
Post by: Theforeshadower on July 20, 2014, 10:53:28 pm: I was adding a boomerang to LTTP Gameboy in Game Maker Studio when I hit a wall. The movement engine is a heavily modified versionof Goodnight's engine. It makes use of solid objects.

Now, when you use the boomerange or have Zelda following you, the get stuck on any wall object. I tried several ways to return the boomerang from move_toward to directly changing x and y values. Either way I try, the boomerang still gets stuck on any solid object between it and Link.

Just wondering what I can do. I also tired setting the boomerang's collision mask to nothing which did not work either.

Instead, to check for collision, you'd want to do a conditional check within the step event like
Code: [Select]
if !place_free(x + hspeed, y + vspeed) { //Collision code here. }
