Easy Trajectory is a simple script that predicts the necessary speed and direction necessary for a projectile to be lobbed towards a pair of target coordinates. The sample file contains everything necessary to get things working. Left-cick anywhere on the screen to lob a grenade towards the mouse coordinates!

It is as simple as calling: GetTrajectory(target.x, target.y);

Makes use of particle trail scripts found here:

good asset ...very handy script

hi is there any way to control the height of the trajectory ,
am not able to contact you via "contact publisher" as its giving invalid captcha every time i try to do so .
for example is it possible to get path with bit lower height of trajectory arc
also is there any way i can control the speed of object travelling from point a to b with the help of getTrajectory(x,y)
