I suggest you, to create your own "function" (basic function)

try this (I didn't even test it)

Код:

SetPlayerGravity(playerid, Float:gravity) {
    #pragma unused playerid
    SetGravity(gravity);
    return 1;
}

example:

Код:

CMD:gravity(playerid, params[])
{
	SetPlayerGravity(playerid, 0.008);
	return 1;
}
