What's the most efficient way to move objects in 1 direction

Hi,

what's happening in my game is that you are falling endless and you can pick up coins while falling. To make this work, the coins get spawned on the bottom and move to the top.

They get spawned every X seconds (most likely between 1-5).

Do I use the bullet behaviour?

8 Direction Movement and simulate a Control?

Set the Y. Axis every Tick?

Which method is the most efficient for an app? Thank you

I think the "Set the Y. Axis every Tick?" method would most efficient for this app,

But I would recommend using the dt system expression when setting the objects Y value every tick,

eg.

Coin.Y = (Coin.Y - (COIN_SPEED * dt))

yes I thought so. I used this in my last App and it worked just fine.

Far too many people depend on behaviors , anytime you can do with events what you need then I recommend avoiding behaviors , too me I prefer more control with events .
