Question on Delta Time

[Chasech]

Hello again,

This might be a dumb question, but I’m slightly confused on how we are using the Delta Time function. I understand that it is used to return the time between each frame, but how does that allow us to start thinking in terms of pixels/second and how we use it in character animations? Can someone break this down a little more for me please :)?

Thanks!

Hello,

I have a post here that may help you:

Purpose of deltaTime

Let’s say you had a frame rate that was really bad and getting progressively worse. It started at 10fps, next frame it was 6fps, then 3fps, then 2fps, then 1fps, etc. In a line like this, you can see that Time.deltaTime is used to mark the passage of time: timer += Time.deltaTime; So let’s say we are using this code for a simple timer to keep track of how much time passes. This is considered “framerate independent” because it must keep track of time regardless of our frame rate. Our timer …

That is actually incredibly detailed and exactly what I was looking for, thank you for sharing that. I couldn’t quite wrap my head around why we needed delta time, but that example of the two systems (one using frame rates and one using delta time) cleared that up immediately.

Thanks again!
