This is basically from editor templates "Physics catapult"
I try to make a dotted line / the aiming arrow..
here is the .c3p dropbox.com/s/bqn6eb4zq0ppxo2/Physics%20catapult%20Arrow.c3p
So far I only think about using Tiledbackground to trick the empty space/alpha channel when repreating images (between each dot)
and I use another helper sprite, because I cannot add image point to tiledbackground for sprite arrow head positioned along aiming (is in touch).. but the arrow head still rotate/move to incorrect position.
Any better way to do this ?
