[Include] Player Gravity

A simple include that provides two functions for player gravity, one to set and another one to get.

PHP Code:

---

SetPlayerGravity(playerid, Float:gravity)
GetPlayerGravity(playerid, &Float:gravity) 


---

Both functions will return 0 if the player id is not connected, otherwise 1.

If the gravity is set by the server through rcon or SetGravity, GetPlayerGravity will return that new value.
