Hey i want to make an object bounce when it reaches the ceiling. I know about pre defined methods, i want to make it manually.
I stuck at the point, that my object wont come back when hit the ceiling. (I used global_position, because this node is nested inside player node)
extends Area2D
var speed = 100
func _process(delta):
if global_position.y < 0:
global_position.y += speed * delta
else:
global_position.y -= speed * deltaYou have to do someting a little more like this:
func _process(delta):
if global_position.y < 0:
speed = 100
elif global_position.y > 500:
speed = -100
global_position.y += speed * deltaI still got issues understanding how reflections work, i am reading https://docs.godotengine.org/en/3.5/tutorials/math/vector_math.html#reflection since days and cant fully understand how to use it in different ways. They briefly explain how it work with move_and_collide() but id like to understand how to use reflections from the scretch.
Any good tutorials anyone knows?
the easiest way to do a reflect-bounce against an ideal flat surface, is to reverse velocity x or y(depending on the surface wall is horizontal or vertical).
e.g:
velocity.x = -velocity.x
If you want, the fancier way of doing it yourself is by reflecting your velocity vector off of the surface you hit.
Here's an explanation of the math that does the job.
This way you get the right bounce regardless of what way the surface you hit is facing.
The easy solution by MagickPanda worked pretty well with stationary borders.
While i am trying to figure out the mathematical approach of award , i try to reflect (bounce) several Area2D's from eachother when touching each other.
Reverse the velocity (x & y) didnt worked out.
