im developing a game using andangine and the tmx and body2d extensions. i create Objects(sprites) like coins an specific positions while creating my map. i use a contactlistener to check if the player collides with a coin.
how can i delete this sprite? and how can i organize my sprites best? thanks =)
I assume you create a PhysicsConnector to connect between your sprites and bodies. Create a list of these physics connectors, and when you decide you should remove a body (And its sprite), do the following:
Body bodyToRemove = //Get it from your contact listener
for(PhysicsConnector connector : mPhysicsConnectors) //mPhysicsConnectors is the list of your coins physics connectors.
if(connector.getBody() == bodyToRemove)
removeSpriteAndBody(connector); //This method should also delete the physics connector itself from the connectors list.
About sprites organization: Coins are re-useable sprite, you shouldn't recreate them every time. You can use an object pool, here's a question about this topic.
