1 pointI'd looked at this problem a few weeks ago, got 90% the way there looking at some other odforce posts, this inspired me to finish it. The idea is to first calculate the angle between each curve segment, then apply it in a for each loop so each segment is rotated by the total of all the previous segment angles, at the correct pivot point. curve_unroll.hip
1 pointI am trying to create some collision particles that appears when metal collides with surface. Right now the particles are emitted from the ground with the velocity of the ball. I am not sure the particles should be emitted in the direction of the ball travels or opposite to the ball travels. I think it should travels in the direction of the ball but backwards looks nicer. Which version do you guys think is better? Also anyone have a good reference for this kind of sparks?
