Ok, so, the game I'm making uses a lot of collisions, which trigger reactions. For example, there is a seesaw, and when the ball lands on the end, it flips (like a seesaw!). And a cannon where when the ball lands in it, it shoots it out. But the problem is, when you have multiple items (that are the same) when the reaction triggers, all of the other items of that kind trigger too. Does anyone know how to fiz this? (It is NOT pick one at random.)
You need to change the "subject" of the event so that it concentrates on one object. For example, "If seesaw collides with ball, move ball" would move all balls on the play area, but "If ball collides with seesaw, move ball" would make MMF recognise that you're referring to the specific ball that hit the seesaw.
(This might actually be untrue for collisions as I haven't tested it, but a number of events do work like this.)
To make your objects unique, you could consider using Spread a Value. I'm not actually sure of the specifics, but a search in the Articles section might help.
Im using TGF by the way. Also, not all the balls move, only one, but the problem is that all seesaws would flip instead of just one. But ok, Ill try switching subjects.
