Creating a beam of light. Is this possible?

Macca_McGill · September 2011

Hi again everyone,

Basically i'm wondering if it is possible to create something that will replicate a beam of light? I want the light to start off emitting from an object, in a straight line. But, they need to make the beam of light reach another object, using reflective objects.

So this beam of light would need to reflect off different surfaces in different directions.

Is this possible with game salad?

Thanks in advance.

I think it might be possible with GameSalad, but not easy. In , I made a Laser as one of the 4 main weapons. During the game creation, I thought about having the laser bounce off of reflective surfaces. That's tricky, because then the laser line has to change in length... and then a second (or more) laser has to spawn relative to the position of collision. It's some crazy math... and probably creative level design too.

Special effects could be used at the angles, to hide the straight edges of the actors. The hardest part would be determining the size of the laser beam, based on the actors it touches — VERY DIFFICULT if the source of the laser moves. I think invisible sensors could be sent out to determine where the point of collision is occurring.

Sounds like hard work then haha. I relish a good challenge though

Ive added a link below which shows a basic concept for maybe the first level.

You will have an actor that emits the beam, and a target actor the beam must reach. Neither of these actors will move. As you can see the beam of light emits from the start, the user must place the piece in the correct place to reflect the beam to end end actor.

Obviously, as levels progress the start/end points will be in different places and the user will get different pieces to manipulate the beam to get the end.

That first level could easily be done with GameSalad, as you have all of the necessary data... the start of the laser, the bounce point, the angle of the bounce point, and the end point. I think snapping the pieces to a grid might make it seem more precise.

Ok, thanks for the quick reply. You know any good tutorials for where to start with creating this? Lol. Not the actors or stuff, mainly the light beam and how to chanfe its angle etc when it bounces?

Thanks

might help with the math... like magnitude, vector to angle and cos/sin... but I didn't put a laser tutorials in there.

For each laser bounce, a new actor is needed. I don't think continuous updating of the beam is going to be easy. That's why I think tiling is a good idea.

Depending on how complex you want the laser to be, this could be a very challenging project.

it;s possible because Tendrmers connects template uses beams of light
