I need some for my newest game, Laserfield.

Be more specific please, so we can tell you exactly what you need. smile

Are we talking light physics, like what happens when you shine a beam of light on a mirror?
You'd need to find the mathematical formula for that, I think, and then recreate that formula in a script.

when gf clicked
go to [startpoint v]
point in direction (start direction)
forever
clear
pen down
repeat until <<touching (reflective colour)?> or <touching (reflective colour)?>>
move (10) steps
end
if <touching (reflective colour)?>
point in direction ((direction) * (-1))
end
if <touching (wall colour)?>
stop script

that's a simple, one way beam script

^^^
If touching reflective color or wall color.

do you want info like reactions to hitting lenses?
here are some:

+++-------()<()====)(>()---
() is Convex lens
)( is concave lens
+++ is laser emitter
------ is thin light beam
==== is thick light beam
< is beam getting wider
> is beam getting thinner

Not like this..

I want the laser to be like my project, pen experiment.
There are 2 handles to the laser beam, one on one side, and the other on the other side of the laser beam...
And there should be room for 4 handles...

Help!

Bump!

Sorry, i want to help, but i have NO IDEA what your talking about hmm

if <touching [Reflective Mirror v]?>
change x by (([sin v] of (direction)) * ((0) - (move speed)))
if <touching [Reflective Mirror v]?>
point in direction ((180) - (direction))
else
    point in direction ((0) - (direction))

_

         change x by (([sin v] of (direction)) * (move speed))

The

 change x by (([sin v] of (direction)) * (move speed))

should be outside of the else condition, I just don't know how to do it with scratchblocks - it shouldn't be inside the if else. smile

Did it for you.
