How to make a Static2D sprite move toward a specific point?

Hey there, I’m trying to make a fire wall in my game move towards the right without any input at a constant speed in GDScript in the 2D workspace. It is not a solid object - the only collision would be with the player, which then triggers the killzone script. The problem is, I’ve been thinking and thinking and can’t think of a way for it to work! Would anyone be willing to help me?

I’m using Godot 4.3 and am relatively new to coding.

The thing is:

  • do you want the object to move based on physics with a velocity and experiencing collision and calculating context?
  • or do you just want it to move to a destination without regard to physics or collision?

For the former, you would need to convert it into an object that can experience physics, like a rigid or characterbody.
For the latter, you can just do a tween from its current position to its end position.

`create_tween().tween_property(YOURSPRITE, "position", Vector2(GOAL.X, GOAL.Y), DURATION)`

During its movement, your character or itself need to detect the other via area2d and trigger the killzone script

What is a Tween?
A tween is a simple animation that adjust a value of an object from current to destination. It can be a value that steadily increases or decreases, it can be a color, it can be its size (AKA: scale).
The full logic is written as such

var tween: Tween # we create an object of type tween
tween = create_tween() # we initialize the tween. it will now run instantly
tween.tween_property(object, "property", value, duration) # we set its tween property so it can change it over the set duration until it reaches the value.

Documentation: Tween — Godot Engine (stable) documentation in English

This would depend on your exact game but a fairly easy way is to just update the wall and move it each frame useing somthing like
funs _dealt(Time)
%wall.global_possition.x += 1
