i am currently working on a 3d game i would provide screenshots but i cant see an option.
My problem is that when i unlock a door it is suppossed to dissapear to let the player through but when i use bluedoor.hide() it stays invisible but my character still collides with it. is there a certain way to remove its collosions so the player can go through? thanks.
