Straight-Shot arrow movement.

[Azeroc]

Right, I need formula which would set height of my dummy missile depending on cliff level, to create straight shot. Like now it does like this...

It doesn't go straight. I need formula for height changing so it would go straightly (like a bullet), like this example.

One good fellow in THW said that some friend of his gave him this script which is used in Elimination Tournament (and such dummy missile movement I need as in that Elim Tournament).

 z = Sin(Atan2(Z,maxDist))*DistanceTraveled

But I don't know where to put it in my trigger so my dummy actually changes height equal to that formula.

I also got few mini-questions:
1. What is "Sin"?
2. What is "Atan"?


*sigh* Some day I should start learning JASS, it would make world editor stuff making for me sooo easier xD

 

[Nenad]

Sin=Sin of an angle, use a calculator to determine, or a unit Circle, this is in radians
Atan=This is basically the Degrees of the angle or 1/Sin/Cos x)

I've got no idea how to make the spell though x)

 

[Azeroc]

Well, I already got formula, all I need is to know, where to put it xD
