mp.game.gameplay.getGroundZFor3dCoord(x, y, z, groundZ, unk);

But i want to use the same function on a server-side. Do u know any function which can help me?

Why can't you use it clientside and send the data serverside (if you need it there)?

There isn't a serverside function.

I want to link marker with ground when server is starting, that is why i can't use client side functions

You can't get the ground Z if the area isn't loaded to the player which is why it isn't a serverside function.
