### Get Impulse force needed for parabolic projectile launch

Unity will actually do all of the simulation for you. Given you are providing the vertical component $T$ of the force, all you need is the horizontal component $\vec{H}$, So all you need to do is ...

### How to draw/calculate a parabolic arch to hit stationary target in Javascript

One way is to predetermine the point shooting to, and also pre plot each point used to get from point a to z. I've used an open source library to simplify this example; ...

### Multiple enemies get hit by arrow instead of one

I disagree with the suggestion to keep track of the target. What you can do instead is have some bookkeeping in the projectile about whether it already hit a target or not (a boolean field should do ...

### Need help projecting 2D projectile motion in 2.5/isometric 2D game

But this is in a 2D plane, basically from the side view, which would be perfect if I was making a side scroller. I am having trouble projecting this XY position into the isometric view of my game. We ...

### Calculating projectile path when fired at an angle, forward

Presumably you started by reading our extensive library of existing Q&A on projectile-physics, and constructing a vector from an angle. Putting those together, you should have no difficulty ...

### How to make a homing projectile make a more objective path to the target?

This is probably what you need. It's for unity in C# but the maths all there. http://wiki.unity3d.com/index.php/Trajectory_Simulation I use this all the time and it is VERY accurate even at high ...

### How to make a homing projectile make a more objective path to the target?

Intercept the target I'm not too familiar with UE, but the behaviour you describe is consistent with the projectile "naively" accelerating towards the target's current position (from your ...
