Hi,
I have problem that I have aiming system using position, and I need to give the projectile some real looking ballistic curve. This are some basic points of what I need.

the part can be in any distance (inside gun max distance)

It must look really realistic

it must look realistic in any distance, so it wonāt be just same curve, but scaled

it will be really great, to have the curve easily changeable

But I donāt have any idea, so can you help me with the logic?

That first thread already contains all the code for firing a bullet with a curve and code to predict the path of bullet, you donāt strictly have to know how the equations got there.

You really donāt. Thereās many resources out there that involves minimal math.

To calculate bullet trajectory (without math) you can use this resourced called āFastCastā, it has bullet physics (as highlighted by the post)

Iām no expert (I really havenāt used this module), but if you do need help, maybe @EtiTheSpirit can provide you with further support. The docs should help you initially set this up.

For me personally, I learned some useful math by teaching myself, so you can be in a lower math level and still learn some useful programming concepts.

Thatās good, but you should learn the theorems and other important things, sine by itself requires learning the Law of Sines. Or with cosine you should also know Law of Cosines, that kind of thing.

If you know how to do the math, you can manage it. Iām not educated in this type of math personally, or I at least donāt know how to get force + initial velocity from displacement. Thereās an equation out there. Just do some googling.
