health

So i need some help cause i don't know any scripting. I need help putting together a script to make a car start with 0 health and every time the player collides with it to add 1 health and when it hits 50 to finish the round. also a script to spawn a specific actor on each side of the screen would be appreciated

You should probably at least consider Stencylpedia before posting really, really basic stuff like this...Anyway...

You can use blocks to create a script like this to spawn actors randomly:
(This would be an event for a scene)
-When created
    Trigger [custom event]

-When [custom event] happens
    Wait [pick random number 5-15] seconds
         Create actor at [give it your own coordinates]
               Trigger [custom event]



Also you should consider starting the car with 50 health and decrementing it by 1 until you reach zero and kill it.  That's kinda how health works...
