How do I make this custom swipe

The path itself can be defined any way you want. The spine suggestion is a valid way to do it. The hard part is dragging the object along a path which is different than having the object move along a path.

My example with an arc just simply moves the object to the closest point on the path. That works well since the path is mostly in a line. I guess just moving to the closest point would work for a triangle, square or circle as well. The only issue in my mind is you can then move directly across to the other side instead of having to go around the edge. Using the closest point wouldn't work well for more complex paths.

My incomplete idea for a better general case solution would be to make the path a polyline since it's simple enough to constrain dragging to a line. Then when a corner is hit it decides which line segment to move on based on the direction to the mouse.

An alternate idea would be to find the closest point and the find the closest distance along the path, and have the object start moving in that direction.

But perhaps the closest point is good enough. That involves finding the distance to all the corners and all the edges and selecting to closest one. The distance to the lines is the more mathy one.

The absolute simplest way would be to put invisible walls around the path with sprites, move the the object toward the mouse with the "move at angle" action, and use the custom movement behavior's "push out" action.

Thank you, i was thinking the same, maybe adding more points to "spine" will make it more accurate .. anyway need to find out how to code that.

Another idea is the curve looks to be an arc on a circle. Here's one idea to constrain the ball to that arc:

To make it perfect you'd need to tweak stuff. The radius, lowAng, highAng, the angle of the track and the origin of the track.

i want this link , can you or anyone please reupload this file ? thanks

thanks a lot :]

and how can i get those variable values for another sprites etc (radius lowAng highAng)?

and what if my sprite was Horizontal or vertical ?

Make a circle sprite and resize it in the editor till the start and end positions are on the edge of it. That's your radius.

Then run the layout and set a text object to angle(circle.x, circle.y, start.x, start.y) to get the lowAng. Do the same with the end position to get the highAng. You may need to swap lowAng and highAng if it doesn't work.
