class: OneTimeCollisionHandler

[26:7] extends: CollisionHandler

Wraps FXGL's OneTimeCollisionHandler (com.almasb.fxgl.dsl.handlers.OneTimeCollisionHandler), a CollisionHandler subclass that fires its action on the first collision, then disables the collidable on the one-time entity so the pair never collides again. Register with the running game's PhysicsWorld (fxgl.getPhysicsWorld().addCollisionHandler in chunk 6). Example: h = new OneTimeCollisionHandler("player", "trap", ::springTrap); physicsWorld.addCollisionHandler(h.obj); public springTrap(player, trap) { ... }
