I made this command tested it, and it is working. When player presses "Y" it will lunch him in the air. Maybe this can help you

Код:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
	if(newkeys & KEY_YES)
	{
	    if(IsPlayerInAnyVehicle(playerid))
	    {
	        SetVehicleVelocity(GetPlayerVehicleID(playerid), 0.0, 0.0, 0.5);
	        return 1;
		}
	}
	return 1;
}

it goes like this

Код:

SetVehicleVelocity(GetPlayerVehicleID(playerid), x, y, z);

If you wwant only in air just remove that 0.5 and set like 5. It will be really high.
Hope this helped you
