This was originally made for GMod 9 by KuroNeko so credit of idea goes to him. I have recreated it for GMod 10. Also some credit goes to Joel_Yeah for starting it off.
M-way is a scripted entity that multiplies until it hits something.
This video can explain it further.
Changes colour depending on state.
Press use to expand/retract.
Wire inputs/outputs are included by not required.
Inputs: Toggle, Expand, Retract
Outputs: Expanded, Retracted
It's a SENT, put the MWay folder in /lua/entities/
I strongly welcome suggestions and criticism.
