'Power' parameter in the shoot command

[ApothiX]

I am attempting to create a projectile using the 'zangle' and 'power' parameters of the 'shoot' command, something like the bows on Graal Kingdoms. My problem is that I cannot find out the equation for 'power' based on the distance you want the projectile to be launched. I'm using a zangle of pi/4.

Any help would be much appreciated. (Please do not simply say "search the forums", as I have done so, but every conversation I've seen about the zangle in the shoot command has ended abruptly before 'power' was touched.)


Thanks,
