How Should I Go About Making Realistically Fast Bullets?

Question

As you know, In real life, bullets aren’t hitscan. They just move so fast, they appear so. I think it would be interesting for players to have to lead their shots on long range. How can I implement this in my game? I see two options:

A: Calculate the delay from the distance and the speed

• Pros : Seems simple enough
• Cons : Idk how to do it

B: Really Really fast projectile, long collision box to make up for it

• Pros : Just a projectile with high speed.
• Cons : I feel like a long collision shape would in some part negate the
  fast projectile effect.

What do you think? Thanks

A. Use raycasts.

B: Really Really fast projectile, long collision box to make up for it

In this case, the “collision box” must be very, very long.

Characterbody3d falling through floor under specific circumstances related to falling.

This option is the closest. Very briefly — the game physics engine is deterministic and does not always have time to process collisions if objects move quickly. Example — a bullet flies through glass. In one physical frame it is in front of the glass, in the next — behind it. The glass remains intact, which is impossible in reality. That’s why in such a case you need to use a beam (raycasts), not a physical body. Therefore, the realization of real physics in the game engine is not a very good …

And also, in real life, bullets fly in an arc.

Awesome idea, actually, thanks a ton. I’ll look at that post
