GET_GROUND_Z_FOR_3D_COORD

Hash 0x24FA4267BB8D2431

Runtime name GetGroundZFor_3dCoord

Lua

local retval, groundZ = GetGroundZFor_3dCoord(x, y, z, p4)
local retval, groundZ = Citizen.InvokeNative(0x24FA4267BB8D2431, x, y, z, Citizen.PointerValueFloat(), p4, Citizen.ReturnResultAnyway())
  • Float parameters: Lua integers (10, or whole numbers decoded from NUI/JSON) are sent as ints and read as garbage. Write 10.0 or value + 0.0. The generated JS wrappers add 0.0000001 to non-zero floats for the same reason.
  • Pointer (out) arguments are not passed in Lua/JS: their values are returned after the result, in order.

One command adds the MCP server to Claude Code. Agents can then search natives, read full docs, look up enums and compute hashes instead of guessing. Every page is also available as llms.txt, Markdown and JSON.
