onCollisionWith()
onCollisionWith(
classOrObject,callback): () =>void
Add a callback to be called when a collision occurs.
Parameters
• classOrObject: any
The class or object to observe for collisions. Should inherit from FComponent.
• callback
The callback to add to the collision event.
Returns
Function
A function to remove the callback.
Returns
void
Examples
const player = new Player()
const enemy = new Enemy()
player.onCollisionWith(Enemy, ({ component }) => {
console.log('Player collided with an Enemy!')
console.log('The enemy is:', component)
})const player = new Player()
const enemy = new Enemy()
player.onCollisionWith(enemy, () => {
console.log('Player collided with the enemy!')
})const player = new Player()
const enemy = new Enemy()
const removeThisCallback = player.onCollisionWith(enemy, () => {
console.log('Player collided with the enemy!')
})
// To remove the callback, call the function returned by onCollisionWith
