How do i create a curving projectile?

You could tween it but then comes the question what if it hit ceiling
Or wall?
You would make logic to stop tween and test if that work
But then based on angle you would need to give different values for X and Y tweens (you would need to use two tweens)
100% doable just if you are new idk if that is best idea

MAYBE do something stupid like i did How Do I Add KnockBack - #15 by ZeroX4

Where there is still option to use physics behavior

On other hand this is aiming but imagine his player is your bullet
You don’t really need line for aiming you just want from his tutorial how to set trajectory for object
