Balrog85 Posted July 17, 2015 Share Posted July 17, 2015 Hi. I'm completely useless at trigonometry and direction-related code. Could somebody please tell me the easiest way to detect if a vehicle is travelling forwards or backwards (or more towards one of those directions than the other), without the driver necessarily pressing the accelerate or reverse keys. I'm trying to stop my server's drift meter resource from awarding points when the vehicle is travelling backwards, as it's easy to glitch it and get a lot of points by rolling a car backwards, down a hill. Thanks. Link to comment
GTX Posted July 17, 2015 Share Posted July 17, 2015 From my old roleplay gamemode back in the days, I hope it can help you. (Its purpose is to check if driver is driving backwards and then do animation out of it.) function checkBackwardAnimation() if isPedInVehicle(localPlayer) then local veh = getPedOccupiedVehicle(localPlayer) if veh and getVehicleController(veh) == localPlayer then local ax, ay, az = getElementVelocity(veh) local m = getElementMatrix(veh) local rx = ax*m[1][1] + ay*m[1][2] + az*m[1][3] local ry = ax*m[2][1] + ay*m[2][2] + az*m[2][3] local rz = ax*m[3][1] + ay*m[3][2] + az*m[3][3] if ry >= 0 then setElementData(localPlayer, "braking", false) else setElementData(localPlayer, "braking", true) end end end end addEventHandler("onClientPreRender", root, checkBackwardAnimation) Link to comment
Balrog85 Posted July 18, 2015 Author Share Posted July 18, 2015 Yes, that's exactly what I needed. Thank you very much Link to comment
