Slippery code for GM

What is a code for an object that is on ice make the ice slippery?

I think it would be pretty hard to do that if the character didn't already use acceleration/deceleration when moving normally (as opposed to "jump to relative position" movement). If acceleration and deceleration are used, I guess you should just make the values of both be lower (i.e., walking/running speed should increase slower and decrease slower) when the character is on top of ice blocks.

Wow. All it is:
Instead of stopping when you hit the ground, set a low friction, like 0.25. That way you slide and then slowly stop.

Already did that and it doesn't work.

Let me show you, put this code in the collision event for the ice object:

Yeah, it doesn't work.

What happens?

Does the character's speed gradually increase/decrease in the game normally, instead of the character just moving back and forth at a fixed speed when the movement keys are held? Because if the latter is the case, I'm not sure slipping on ice could even be implemented, at least in a way that made any sense.

I'm making a platform engine, so you can see how it's done.
