lol poor you, no one replied. I guess I can help you. When you set a checkpoint you need to double left click on it and at the button you will see "nts type" I guess. You need to choose vehicle, air or boat. If your checkpoint is blue ( RGB = 0,0,255) then make it vehicle. If the checkpoint is red ( RGB = 255,0,0) then make it air. Finally, if the checkpoint is green ( RGB = 0,255,0) then make it boat!. Its pretty simple. If you have more questions ask. @salvadoc17. I'm pretty late, but just saw it!
