Delta

[proper cedar]

multiplying delta with movement useless when delta is less than 1? whats best practice?

velocity.x = (direction * SPEED) * delta

I'm not sure what the confusion is

But velocity generally shouldn't be multiplied by delta like this

Delta should be used when there is a change in a value over time. For instance, if you were applying an acceleration (increasing the velocity over time)

But if you're just setting the velocity to a value, you shouldn't need to use delta, because it has no relation to time.

and if delta is higher than 1 you are having a very very low fps count.
