Some help in object gravity?

[Storsorgen]

Hi there! I've attached an example of my situation here.

I have a mushroom object that I want to go jump on creation, then fall down. Currently I do this by fastloop movement so that it will never sink into the ground. The problem is that once one mushroom is touching the ground, gravity is set to 0 for all the mushrooms constantly, so they keep falling slowly. I don't know why it does this to all of them. I tried using spreadvalues in ID and selecting them by loopindex, and this kept the speed, but it had the side effect that mushrooms that were already on the ground fell through.

Does anyone know how one should handle this?

Tell me more about the game.
Is it big? Complex? Scrolling? Moving Platforms?
How are the Shrooms supposed to act?

Sometimes I 'cheat' with with this by giving the object with gravity a platform movement with a speed of 0, jump strength of 0 and assigning it to player 2, 3 or 4 in a 1 player game (or player 3 or 4 in a 2 player game etc.), and sometimes I add an 'ignore control' action for that player to be extra safe. The only downside to this is to give it the 'jump' you need to make sure you either 'stop' the movement or set the gravity to 0 while it is jumping otherwise the platform movement's gravity mostly overrides your vertical positioning. This could also be done with the vector movement.

It's not big or complex yet. The only problem I have with the mushrooms is gravity, horizontal movement or moving platforms I can deal with. It is scrolling.

The mushrooms are supposed to behave in the way that when they are created, they jump up, then fall down, once.

Im guessing all Shrooms have their own Gravity_ Alterable Value...?
In that case you could try:

If Shroom overlaps Backdrop
- Shroom set Y position to 'Y position - Gravity_'
- Set Gravity_ to Max(1,Gravity_ / 2.0)

May make an example later on if you dont get it.

King:_cool, if you check my example that's pretty much the solution I'm using. The problem i'm having is that when one shroom collides with the background, all shrooms get adjusted gravity, meaning I can't properly discriminate between objects while inside the "shroom loop", and I can't figure out how to incorporate a working loopindex reference.

[King_Cool]

Didnt check out the example bfore now.
Here ya go.

You pixel perfect collision without any loops or extencions.
You can also alter how much Gravity is increased each Frame ( see Shrooms AltValue ).
Shroom are also able to collide with the ceiling of the Platforms ( while bouncing up ) without any problems.

King_Cool, that is absolutley brilliant! I can employ this method of gravity in many other things too, you're a genious!
Thank you very much! If there were any trophies I could give away, I would.
