i was making a linerider clone a while back and you can actually get it to draw lines quite quickly if you do it right.
have you searched for this? i'm sure i've seen a tutorial or example somewhere before.
if you're not using MMF2, it's going to be a lot harder. you'd have to probably use trig to create a line out of loads of small active objects. there's also the drawline object but it is very buggy and sucks.
A decent example of exactly how to do what you wanted, if you expected someone to tell you how it was done with the draw object, mention that before hand. Otherwise, we're going to give you a better way to do it without it.
So then what are you asking for... you got a nice example of how to do it, but in response to it you just say "I'm good with the draw object though." and now you're saying you don't want to use the draw object.
Hmm.. I'd like a laser example without using the draw object. Haven't opened that example yet, my MMF2 is at home, though.
