Hey, Dcrew here!

Just wanted to show off a creation here. (PM me if you wonder how it's done)



The line is always between the Player and Enemy (can have as many enemies as you want) and set's the line's width to the distance between the Player and Enemy and set's the angle towards the Player and it's position at the Enemy.

When the Line touches obstacles or walls or (anything you want really) it turns Red. thus meaning it cannot see you! But when it's green it can see you, thus making it aim at you and see-ing you!

I think this is a really good idea for enemy AI in games and will go great with Pathfinding :D

Thanks!

You should post the cap and/or exe.

Edit: I edited the topic name to state it is for C2.

This is great, and would probably work with platform type environment with a little tweak... would it be simple to add restrictions to the angle the line is able to move? ie... restrict the enemy's field of view?

I'll try fiddling to see what can be done.

@plauk, it would probably be easier to add conditions to when you are seen rather than restrict the line's movement. I'm using a similar system for my game, and though I'm not up to that part yet, I've given it a lot of thought and that seems to be the way to go.
All's fair in love and war, kid.

@plauk It would be super easy to do that. Just make it so the line will only go green (it can only spot player) if the distance between the two are below 400 (or w/e you want)
