Slippery ice platforms?

[N64Mario]

Is there a certain way to make slippery ice platforms work using custom platform movement? For example, you shouldn't be able to move right away when you're standing on ice. When you move right, and attempt to move left, you should not immediately move left. There still should be movement going right, but slowly decreases.

I'm just wondering how this would work in a custom platform engine.

Just alter the acceleration and deaccerlation. Have an invisible object around the ice that causes it to switch. When your character is not overlapping it, have the accerlation and deaccerlation change back. The rules to to do this should be i nthe events editor in the "then" statement.

Hmm... But by default my custom platform movement does not have any acceleration/de-acceleration to it. It's an exact pixel movement based on using fast loops, & DavidN's fast loop platform tutorial. Will that change how I code an ice platform?

You'll need to make holding a direction gradually increase the horizontal value (by adding to it rather than setting it) and then set up an alternative event for walking left/right while on ice, with more gradual acceleration.
