Add Force 2D vs Tween

[starfox]

Hi everyone, let me preface by saying I'm new to Unity and Playmaker.

I am wondering the best practice to move a bullet? In my case I am using Unity 2D and 2D physics to make a side view shooter like space invaders.

Should I be using 'Add Force 2D' and then checking for a collision with the edge of the screen (or other things) to remove the bullet?

or

(I have the DoTween Pro asset and the DoTween/Unity Actions asset) Should I use a DoTween 'Rigidbody 2D Move Y' instead?

Which would you prefer for the right blend of performance and ease of implementation?

Are there rules around best practices for moving a bullet with Playmaker and Unity 2D?

Thanks for any help! I look forward to growing with this community and sharing tips.

Hi, im sure you have solved it by now, but for the sake of there being at least one answer to your question:

Firstly I also am a noob.

I used this tutorial and found it very useful:

This is part4, where you learn to make melee and shooting attacks:

It is totally playmaker based.

As a noob I can summarize what he does as:

- Upon shoot button being pressed Creates a projectile object (which he saved as prefab previously) and adds velocity to this object in the correct direction.
-Upon spawning the object waits a set time before going to a state with 'destroy self' action.
-The object is tagged as projectile and enemies are FSMed to react on triggering the projectile tag.

Hope it helps someone.
