How do I set a gradual max speed?

Hi all.

I have a 2D platformer with two movement speeds - walk and run. Walk is 300 max speed, run is 600 max speed.

The player holds L to run.

I'm using the code below. The problem is that as soon as they stop running (letting go of L), they immediately drop to the walking speed of 300, and it's a jarring difference.

How might I make the speed drop from 600 to 300 over the course of a second, rather than immediately please?

You could instead use a variable for speed and tween that variable from 600 to 300.

Ah, I managed to figure it out!

I set the walk and run speeds as variables, and created a tween between the two on release of the run button.

And I have a listener waiting for when the tween is playing - which updates the Platform maximum speed to match the tween.
