Need a growing Laser?

beefy_clyro

Hey. Im having a little trouble figuring out how i would do this. Basically i have an actor that can move around in a big square, i want to be able to fire a laser which grows in size from the actor until it hits something, whether it be something in the square or the squares walls/edges.

Any ideas greatly welcomed and appreciated.

IIRC, changing an actors size leaves the original hitbox, correct?

Look on the power bar, it should give you a basic idea.

If I wanted a laser to come out of a gun, I would do something like
Interpolate self.size.width to 50
Constrain self position x to (gunX +( gunWidth/2))+(laserwidth/2)

I'm a little confused about what exactly you want. You may want to do this.

Self Boolean - collided (false)

If collides, change self.collided to true

Every .3 seconds,
If collided is false,
interpolate self.size.width with a duration of .3

Make sure the duration and timer are the same.

Imagine you are in a square that is 200 tall. If you are at the bottom on 0, i would need the size of that beam to go from the gun to the top of the square (200). Now if something moves in front of the laser at say 150 from the bottom, the laser needs to hit it and change its size to that. If the gun moves up to say 100, the laser needs to go from there till the next point it collides. so the laser should shoot 1 solid beam, it constrains to the gun and continues on growing in size till it hits something and then adjusts its size to that.

Oh good. I thought from the title of this thread that this was more spam for Viagra.

beefy, maybe try some reverse technology on the tutorial for the health bar from tshirtbooth? It's basically the same thing but in reverse…kinda.

Haha yeh i can see how you may of thought that.

I don't think that will work. The whole idea of changing its size based on a number is fine, but with health, you would start at say 100 and work down. The problem is, the 100 in this case will always need to be changing. If for instance you are close to the wall your laser may be as short as 20, if you are far away it maybe 200, if the laser is straight at say 200 but something comes in front, it needs to adapt to that.

Maybe check out GS connect template. Seems to achieve a similar result.

@SlickZero My thoughts as well, but was thinking Space Balls...
