Question

I’m creating a multi-player platform game in Cocos2D (objectiveC). I create dynamic bodies for the players as it applies gravity and platform collision however I don’t want the players to be able to push each other characters (while fun, too much grief). What is the best way to achieve this?

Thanks

Answer 1

You can set the b2Filter data of an object, setting the groupIndex of bodies to the same, negative number means they don’t collide with each other. b2Filters are set on a per fixture basis. (LINK)

//Objects with these fixtures won't collide as they have the same, negative, groupIndex
fixture1Def.filter.groupIndex = -1;  
fixture2Def.filter.groupIndex = -1;
