You must use a value between 0 and 1, with 0 being the beginning and 1 being the end. ✓ Path Speed: Use this Action to change the speed of the Instance on the Path. Negative speeds move the Instance backward. If you use 0, that will temporarily stop the motion along the path.

Here are your options: ✓ Jump to Position: GameMaker checks the position of the Instances, such as checking to see if the Object left the Room. If the Object does leave the Room, you could have it reappear at the top of the Room by jumping. Another example is if a player dies, and you want the player to restart in a specific position. You specify the X and Y coordinates to determine where the Instance jumps to. ✓ Jump to Start: Use this Action to move an Instance back to where it was created. Figure 4-4: The Jump Actions from the Move tab.
