Trajectory prediction system from Castles Battle!!!

That is system from "Castles Battle" mini-game!
Just copy the lua!
Note: this code useful only for mini-emitters!

There are five variables what you need to change:
id = {{4,0},{75}}
First number is id of mini-emitter, second - activation socket for calculating trajectory (not requied)
vel = 40
Emitting velocity (that you setted on mini-emitter with slider)
timem = 50
How many lines lua use for visualise a trajectory line
time = 4
Changing lenght of trajectory calculating
width = 0.5
Width of trajectory line
