How to make bullet relative speed in comparison to player?

If I have a player moving to the right, shooting the bullet to the left (backwards) the bullet seems to be going pretty fast. However, if I shoot it the same direction i'm travelling to the right (forwards), the bullet seems to be going slow because the bullet doesn't have momentum of the player travelling. Is there a way to make the bullet go the same speed in relation to the player?

This is a top down shooter where the player can shoot in any direction.

You can adjust bullet speed, when bullet is spawned set bullet speed to (self.Bullet.Speed+Player.Platform.VectorX)

You should probably do this on every tick, otherwise the bullet will continue to move too fast or too slow when the player stops:

set bullet speed to (self.BaseSpeed+Player.Platform.VectorX)

dop2000 Thanks for your help. Sort of works, but it's only vectorX (doesn't work for shooting up or down) and seems to shoot faster when shooting in the opposite direction as the player vector is added to the existing speed.

Here's a c3p file to show you the current issue:

Any help is greatly appreciated! Thanks again!

Sort of close. Shooting forward seems to push the bullet correctly, but not when shooting back. Also, when I move the player up or down, it drags the bullet up or down as well.

Since I'm working with dual analog controls, maybe I can detect whether the movement and aiming is at around the same direction and add a little more speed. Was just hoping for a more simple logic.

If you don't adjust bullet speed on every tick, then it will have a different problem - bullets shot in the same direction when moving and when stationary will have different speeds. Demo:
