Jumping Method

[IvoHD]

Hello,

I have a simple question about Rick’s approach to the OnJump method.

Here is his approach:

Here is mine:

Why should I check if value is pressed? Doesn’t the method only get called if the key was pressed anyway?

Hi,

In many cases, there are multiple ways to make something work in Unity, and Rick cannot show all of them. If your code works, it’s a solution by definition. I think Rick wanted to be on the safe side because we cannot know if OnJump will get called only when a key was pressed. In programming, we often check for certain things before executing a code block even though we are sure that the code will be working. A lot is going on during runtime.

Did this help?

Hey,

I guess it’s saver in case the method gets called anywhere else by accident.

Thank you!
