What problem are you having? What have you tried so far?
At the moment I am using a green sprite and the event
Park_open [name of sprite] is overlapping player, set color to rgb(100,0,0)
Player set position to Park open (image point 0)
It's coming up a weird brown colour, like it's adding the red to the green. I also have a red sprite but I have no idea how to use the animation or even if I can, because I am using the free version.
I wanted to make it that the car can't move once it is "parked" but at the moment, as soon as the sprites touch, it activates.
