Hello, GameMaker Community! I just started using the software a few week ago, and I am following Shaun Spalding's guides on Youtube. I successfully used the method he taught for interacting with a powerup object. The thing is, I can't get it to work when the powerup object itself is a second player, in a two player project. The idea is that colliding with the second player object will increase the jump speed & moving speed of the first player, change its sprite and destroy player 2. Player 1 is obj_lotem and player 2 is obj_guy. under "create" event in obj_lotem: under "step" event in obj_lotem under "collision" event in obj_guy: I made sure several times the spr_lotem_big exists and is spelled correctly. What happens is that obj_guy disappears (as it should), but obj_lotem won't change it's sprite, moving speed or jumping speed. I don't think i needed the alarm part because I don't want to use this as a temporary effect, but a permanent one. Can you help me? Thank you in advance!
