Hi, I've been trying to figure out how to make a platform move to the right just before my character reaches it, say by 4 units and then stop. Thanks!
You want to play with adding a wake component to your platform, select your platform in the assets panel to the left, then on the options panel to the right scroll to the bottom and add component... The wake is measured in pixels. Give the object linear velocity in its options, but it won't move until your wake component requirements are met, then use the sleep to make it stop after your "4 units"
