Forums » Help » On Collision End

I found and setup the collision detection between 2 sprites but is there a way to easily perform action when collision is no longer 'true' for example at http://Mantrakid.com/secret when link walks away from the radio, it shuts off? I suppose I can have invisible triggers outside of the radio area that trigger music to stop? Or is there a better way? Thx!

Well the collision ends as soon as you stop walking against the radio. When a collision occurs, the two entities are moved apart so that there no longer is a collision.

Using an invisible trigger entity would be one solution for your problem. You could also make the radio non-solid (ig.Entity.COLLIDES.NEVER) and use its .check() method that is triggered when both entities overlap.

Or just check the proximity of the player to the radio:

// In the radios update() method
var player = ig.game.getEntitiesByType( EntityPlayer )[0];
if( player && this.distanceTo( player ) < 128 ) {
	// do something
}

Hello, this is old but it showed up in my Google results. You can find the answer here http://impactjs.com/forums/help/fixed-entities-collision. Which is to set the player to a light collision and boxes to active. Works great.
