# Do a parabola while using move_and_collide

Attention Topic was automatically imported from the old Question2Answer platform.

Hi everyone, I have the problem that I mentioned in the title, basically:

I want to go from a point A to a point B using move_and_collide, for x just with the next lines on velocity is working fine:

``````velocity.x -= distanceToTravel * delta * speedLateral
move_and_collide(velocity)
``````

I’m controling if I reach point B comparing the distanceTraveled, until here everything is right, but I want this move doing a basic parabola on y axis, the problem is that I don’t know how to approach to implement it on velocity vector… I’ve implemented it using basic parabola formula and setting the KinematicBody2D position.y and I can emulate it perfectly, but obviously I want it on velocity

Parabola using python example: Calculate a parabola from three known points – Geo-code – My scratchpad for geo-related coding and research

Any idea about how can I make it?

Thanks!

Just so I’m sure I’m completely understanding this, you want to accelerate until you’ve traveled half the distance and decelerate until you get to point B?
