Projectile Motion Help

Unity Engine
1

Hey Guys,

I am trying to get some projectile motion working but it just doesn’t seem to want to work.

I am currently working on an orthographic top down (it not top down but at a 50 degree angle) game. The player is based in the centre of the screen and shoots at waves of enemies.

I have two style of weapons 1) normal firing weapons which shoots directly ahead 2) Arcing weapons, which get lobbed.

So as an example 1) Machine Gun 2) Grenade.

Anyway I need to make the arcing weapons arch nicely and land EXACTLY on the spot I tap. I have them currently going up then down but its just a right angle rather then a nice curve. My second attempt has it curving but it goes up to some ridiculous heights, moves insanely fast and doesn’t land where I tap.

Can someone point me in the right direction to make a nice parabola/curve/arc, which the player is located in the center and doesn’t move, just rotates. The grenade needs to land exactly on the tapped spot and some control over height and speed would be great.

Also I am trying to control it with transforms rather then physics.

Thanks in advance!
Pip

I made two scripts for it: launcher.cs and projectile.cs
I used physics to move the projectile because you probably don’t want it to go through walls.
I can modify it if you want though.

Wow, thats a pretty brilliant and elegant pair of scripts there, Hencz :slight_smile:

Thanks, I will have a look when I get to work. Walls will not be a issue in my case.

Thanks again.
Pip.
