Wobbly floor effect?

[N64Mario]

Using a static platform engine method, if a player is standing still, how can you make a player go up and down a wobbly floor surface effect? For example, if the floor goes up or down a certain number of pixels, my player object seems to have trouble maintaining itself on a wobbly floor/surface that goes up and down. The player gets pushed out of this floor instead of moving with it.

Any ideas?

I'm not sure what you mean by "wobbly floor". It sounds to me you're talking moving platforms...

[N64Mario]

I thought about that, but it's still not working.

Think of a wavy floor. Moving platforms are FLAT surfaces. Wavy floors are surfaces with many slopes, humps, or whatever you want to cal them.

The other example is this. If a player was standing on a huge giant snake. and its body was moving around up and down. Have the player go up or down as to how the surface of the wavy floor is moving.

Ahh so a bumpy floor?

Could you use the overlapping backdrop event and maybe push the player up a few pixels? (set y position: Y(Player)+1) or something?

Reminds me of the last level of Aladdin on the SNES...

I don't understand where/how your movement pushes it.

Well, I have a similar effect as for using slopes. But my slopes code doesn't seem to work if a surface is moved up a number of pixels once.

Do it the same way you should be doing any platform:

Every frame, move the the player as many pixels as the platform moved since the last frame. So what you need to do is:

Record the position of the floor object before it moves.
Then, AFTER the floor has been moved, have an event that says
"if player_bottomdetector is overlapping the floor object, set Y position of player to ( Y(player) + (Y(floor) - lastY(floor)))"

so your code might look like this:


(this records the position of the floor before it is moved)
*Always:
=Set Value A of Floor to Y(floor)

(this is just whatever your code is that makes the floor move up and down)
*When floor shaking flag is on
=Set Y Position of Floor to (452 + sin(timer) * 10)

(this moves the player by the same amount)
*If bottom_detector is overlapping floor
=Set Y Position of Player to (Y(Player) + (Y(Floor) - Value A(Floor)))
