Sprite Pathfinding

Hi im just wondering how would i get to draw a path with curves and i want the sprite to follow it like flight control

First probably you will need path finding algorythm, like this one:

And then you can simply set Sprite's position or tween its position to the path it should be moving.

Thanks will that works with curves

the thing is that the algorithm that you gave me did not work as it is meant to be used with tilemaps i think due to the collision map

Hi @woodlawn1998_1,

Jumper would not be much of used here. Actually, the title of the thread is a bit misleading. Your very problem is not pathfinding, but actually path following. Which is rather different.
What you are looking for is Bezier Curves. I have recently spotted a nice introduction to this on Gamedev.
You can also look into Catmull-Rom splines, as well.

EDIT: Actually, there is something even more simple. Just boils down the line/curve to a set of points, then write a logic to move the sprite from one point to another. It works as if the original curve was approximated by a set of shorts segments.
