Projectile motion with fixed speed

[tin_nim (Nuclear_silencer)]

You can write your topic however you want, but you need to answer these questions:

1. **What do you want to achieve?**I want a missile to fly a ballistic path with only a single impulse applided

2. What is the issue? Egomoose solution has a problem, That is I donot have the time of the ballistic path, I only have the velocity

3. What solutions have you tried so far? Egomoose’s equation is local v0 = (endpos - x0 - 0.5gt*t)/t; where startpos is x0, and g is the gravity, But it required time to be inputted, Which I cannot provide as It is suppose to have a fixed launch speed .

I want a missile to fly a ballistic path with only a single impulse applided

What do you mean? What is your goal? You want the missile to fly up to a specific height before falling? Or to a specific position, taking into account gravity? Or something else?

I want my missiles to get shot up by a specific speed with just a set speed from the start, Then there will be no more accereation, I also want to account gravity, And I want it to fly the the player’s mouse pos if it can reach that position. Essentially, Its a bullet that get shot up into the sky and will hit your target

It sounds like maybe you want something like this:

Here’s some more detail on what to do if the distance is too far. This isn’t really part of your question, but I’ll go into it for posterity Here’s an updated desmos with the max range stuff: Projectile Motion Calculation With Max Explanation: A bit of math to help. The target is only within range when the part under the square root is positive, i.e. [image] We’re trying to solve for x here. But we have another unknown, y (which equates to “the height of the projectile when …
