Question

How to avoid collision between physics bodies in corona ? The application that I am developing makes use of many physics bodies.I want collision to happen between two desired bodies,but the collision is happening between all the bodies in the system.Can anyone help me with a solution?

Answer 1

There is the second method to assign a groupIndex to each object. The value can be a positive or negative integer, and is a simpler way of specifying collision rules: objects with the same positive groupIndex value will always collide with each other, and objects with the same negative groupIndex value will never collide with each other.

local collisionFilter = { groupIndex = 2 }
physics.addBody(object1, {bounce = .2, density = 1, filter = collisionFilter})
physics.addBody(object2, {bounce = .2, density = 1, filter = collisionFilter})
