[FLASH-USERS] 1D laser question

[Norbert Flocke]

Hi John,

In the routine 'ed_createRays1DRec', find the following section (near the 
end):

                     blockID = blockList (block)

                     rayPower = beamPower
                     raySpeed = initialRaySpeed * ed_speedOfLight

                     velX = raySpeed
!
!
!     ...We now need to make sure, ...(comment section)
!
!
                     if (blockFaceMinX) then
                         rayX = xminBlock + cellWallThicknessHalf
                     else if (blockFaceMaxX) then
                         rayX = xmaxBlock - cellWallThicknessHalf
                     end if

and change this to (remove the original 'velX = raySpeed' line and add the 
new velX lines in the 'if (blockFaceMinX) then' section:


                     blockID = blockList (block)

                     rayPower = beamPower
                     raySpeed = initialRaySpeed * ed_speedOfLight
!
!
!     ...We now need to make sure, ...(comment section)

                     if (blockFaceMinX) then
                         velX = raySpeed
                         rayX = xminBlock + cellWallThicknessHalf
                     else if (blockFaceMaxX) then
                         velX = - raySpeed
                         rayX = xmaxBlock - cellWallThicknessHalf
                     end if

This should solve your problem. Tell me what you get.

Best,
Norbert
