I need create custom pie menus via lua,

can someone show me an example for pie menus that launch abilities (like weapons or enhanced movement, etc)

It's really simple. Just look at the coalition grenade launcher or one of the many other things that uses pie buttons and follow along.
That said, here's a brief runthrough:

To the ini, add (with correct tabbing):


And then you make a lua script with the specified filepath and do things from there. Generally people use the pie button to change the sharpness and have a main script on whatever's being affected that does different things based on sharpness. E.g. for a button that'll toggle back and forth between two modes:

how do I create a second type of consumable somethingBar
i need my function, that when the sharpness is set to X, the ability is activated as long as there are a value in the somethingBar. The something bar will be used or decrease by X amount from the over all Y value every somethingsomething miliseconds, so im trying to make it so multiple pie menus will launch different abilities each taking from this over all somethingBar and that whenever this bar reaches empty value all abilities toggle off regardless. The bar should slowly recharge over time too.

If possible Id like it to work with pie menus but im not against using items that require this bar to have energy too or hidden button commands so I dont overload the actor with pie menu slices.

also misc question, how do I create a script that changes the jump script/jetpack script of the actor and switches back when its toggled off?

A bar is really just a number with a nice graphical representation. For how to implement the bar, take a look at a mod that uses one (e.g UNSC shields or flamethrower) and work off of that, since I can't remember the exact code. It's pretty straightforward though.

Outside of that, the rest is trivial. Using the pie buttons to change sharpness it would be something like (I'll also include a cheap and easy way of increasing jump height):
