Map collision

LinkCraft

How do I take a sprite and let it bounce around on a map with gravity so it will stop bouncing at some point and have it bounce off of things in the correct direction and not just up and down?

For bouncing off the map, try something like this:

// Collide your sprite with the map
collisions = collideMap(my_sprite)

// If there's a collision...
if len(collisions) > 0 then
	// Get the collision resolution (a vector representing how your sprite was pushed out of the map)
	res = normalize(collisions[0].resolution_a)
	
	// Get the current speed of your sprite
	speed = getSpriteSpeed(my_sprite)
	
	// Use reflect on it to determine the new speed, and multiply it by 0.9 so it'll stop bouncing eventually
	speed = reflect(speed, res) * 0.9
	
	// Set the new speed of your sprite
	setSpriteSpeed(my_sprite, speed)
endif

Gravity would probably look something like this:

my_sprite.y_speed += deltaTime() * 30 // You might have to play around with the number here to get the kind of feel you want

Hope that's able to help!

Thank you that was exactly want I needed. I was over here messing with 30+ lines of nonsense.
