[How do i] Math for Artillery

Hello,

im not that good at math, and construct 2.

And now i want to simulate an artillery.

First, i need to simulate the angle the barrel is at.

Second, i need the correct gravity and acceleration.

If i have those two factors it should work out.

I have something like enemy.X - (enemy.x/2) (repeat the same for y)

in the head for the angle of the barrel.

but since not every shot is landing correct, this isnt working out.

How should i handle these two factors so i could simulate an artillery?

Anyone know?

really frustrating ...

You're not very clear. Do you want a formula for hitting a specific target? Or do you just want your artillery to shoot properly?

i want it to hit a specific target,

better said, to hit a specific X,Y Point.

and the problem is setting the barrel of the Artillery unit in the right angle to do this.

I recommend to read this page about trajectories:

http://hyperphysics.phy-astr.gsu.edu/hbase/traj.html

It can be little hard to understand at first, but this page really helped me to do trajectory calculations for 3d space.

Sry but im not that good at vector, i cant even make tests how far the projectile would fly, i tried:

if Projectile.Y = Barrel.Y , then set global variable Distance to Projectile.Y - Barrel.Y

But that wont work, i dunno why...

So when the y-coordinate of the projectile is the same as the y-coordinate of the barrel set the global variable to 0(if they are both the same deducting them will always be 0)?

I don't think this is what you are trying to do. But this is what you are doing.

Now the question is what are you trying to do?

oh sry i meant Proctile.X - Barrel.X

i tried to figure out how far away the bullet would fly so i could calculate the ca. Angle of the barrel if the enemy would be that far away.

this was my second option.

But of course i stould would love to calculate the Angle ingame without having it pre-defined.

Link from the FAQ

good link, but i dont understand a thing in that CapX, i only want the end destination, i dont care about how it flies, just where it lands.

To know where something lands, you will have to know how it flies.

sound logic, but when i dont understand how it flies, i cant understand how to find out where it lands.

Sounds logic. So it seems you should learn to understand how it flies.

On the first page there is a link to a page that explains about trajectories and a link to a capx that calculates trajectories.

These will be very helpfull to learn what you need to learn.

You could also choose to create a custom movement, so you can make the trajectory simpler and the landing spot easier to calculate.

good idea with the custom movement, im going to look at it when i finally get the 140 beta update, its not on steam yet...
