Collision Shape

edited November 2011 in Working with GS (Mac)
Hey Guys:

I'm learning to program with gamesalad and I have one cuestion for you:
How can I do Gs use an irregular shape to collide an actor (PNG image) with another actor (PNG images with transparency)? I've seen in GS you can choose only rectangle or circle.

I have a ball and a triangle png images but I can't do a good collision. Any suggestion?

I'm doing something wrong .... right?

    Yeah, as RKS said, we do not have custom collision shapes yet, I really hope they get it our there though. It would make this a whole new world. :-)

    what a shame! It would be helpful.

    I hope GS allow custom collision in the future.

    Thanks RKS and Braydon_SFX.

    There is a way to do it, but it's my own little way that i'm not sure if other people use.
    You constrain invisible actors together to build the shape you want viola!

    @ozboybrian That might work if your building a small game. However, probably not the best idea to do that method if you are making an 18 MB game.

    Also, rotation will not work properly if you do this.

    Actually, anyone know how to make rotation work with constraints? Would be good to know.

    yes by getting the starting angle and using sin ans cos. might need to plug magnitude somewhere in there as well but not sure havent done this in a long time

    @John

    Sounds kinda messy...

    @SkyMaple

    Just some trig.

    Search: DEMO_Wielding_Lightsaber in the new section of the gamesalad creator. Its a free demo that constrains a lightsaber to the player and has rotation working with sin and cos

    cheers
