      Hey Wayne,

      I’m trying to work on the obstacle drop exercise, and i’m trying to get the ball rolling down the slope. However, these weird arcs form when i’m trying to make the ball travel in a straight line, and it just causes the ball to clip through the slope.

      Here’s a video of what i mean: https://www.youtube.com/watch?v=1Qopz_ImYTs

      Using linear interpolation would make the ball travel in a straight line, but it doesn’t add any acceleration to the ball unlike bezier curves, and i think adding keyframes between the two main keyframes to adjust the vertical height ends up being finicky and ruins the flow if i want to change the timing of the last keyframe (when it reaches the end of the slope). Is there a way to fix this?

        I think you may need an extra key frame at the end. So you make the X curve as straight as possible to avoid the ball curving, use that extra keyframe for holding it and then bend the curve when it hits the ground. Kinda hard to explain by text, I don’t know how Wayne does this. Maybe you can upload the file so we can tweak it a bit?

          Looks like you need to adjust the Z handles..

          Wayne shows this in part 1 of this exercise. Scale and rotate the handles until it looks better. You will have to fiddle a little to get it right.

            Hi Tsz.
            This is part of the video lesson, and the challenge with this exercise.  You need to adjust the interpolation between the key frames.
            I show how to rough it in during the lesson and then changing the handle type to automatic to solve most of the issues.
            Let me know how to go after watching me roll the ball down the ramp in the video.
