'Laser' Shooting

Hey guys... I could do with a little help on a couple of things to do with programming a laser.

The first laser question is this:

Is it possible to create a line at runtime that is at a certain variable length and direction? For example, a cannon could aim at the player, then shoot a laser in the direction of the player and the laserbeam would be the length from Cannon to Player.


Second question:

On a different game, I want the player (a spaceship in a side-scroller shooter) to be able to shoot a bouncing laser beam. This would be similar to a bouncing bullet, but obviously 'longer', and it needs to kind of go into a V shape around corners (as a long stream of bullets fired in the same direction would appear to do). I need this to be limited to 1 object though, so a long stream of closely-packed bullets won't do.


Thanks!

For your first question, scaling and rotation is the answer. You change the length of the object based on the distance between the two and change the angle in the same manner.

For the second question, bending objects are not possible in one simple object. You would need to use the Sphax VectorialCurve object. I'm not sure if it has been released yet.

Thanks :)

How do you retrieve the angle, though? I know how to get the distance. Will I need to use the Advanced Direction Object?

Use the Clickteam Movement Controller object. It can calculate both the distance and the angle for you. If you have MMF2 build 243 or later you have it.

I made a game like that where I set the cannon/gun to always aim at your player. If you want it invisble, you can, I didn't. Then whenever you move, the cannon will "look" at you. Then set it to whenever it shoots and object (on a timer or whatever) to shoot in its direction. It worked great on my game.
