How do I?
 

How do I make an object do something when another object is within a certain distance of it (ex. a bullet and an enemy) %(

Pull an if statement out of the bottom

Then go to your object, click it, and then click "functions", the third option. Then, drag the "object distance to object" function to the true section of the if block, and fill in the correct parameters.

Fiddle with the distance until it works, and voila, it works.

Thanks
 

Thank you very much.

If you need anything, just ask me. :)
