Requirements:
To have any unit that can "slide"(Air units, archon/templar, workers, etc.) to have a target to attack
Instructions:
This is really simple to do, if you understand it. This will make any of the following units lose their movement animation, but still move!:
Tassadar/Aldaris: Lose their blue glow.
Terran/Protoss Air Units: Lose their jets and bob up and down.
Zerg air units: Move bodies slower/flap wings slower.
SCV: Lose jets.
Drone: Does not move its tail.
First, you need to move them at full speed towards the
target. Once full speed is reached and you are in attack range, tell
the unit to attack, but keep rapidly right clicking on the
ground after that. If you have done it correctly, the unit
won't stop moving to attack, and will lose its shadow.(Thanks MrrLL for
discovery!)
