When you press handbrake it should draw the image named 'crosshair.png' on the target, but this does not happen. What can be the error? The debugscript 3 does not output any errors Here's the code : local SHOOT_COOLDOWN = 5000 --Cooldown between homing shots local LOCKON_TIME = 100 --Time required to lock on to a target local LOCK_RANGE = 330 --Maximum distance between you and the target local LOCK_ANGLE = 0.95 --(in radians) We cannot lock on targets unless they are within this angle of the front of the hydra local VALID_TARGET_FUNCTION = function (vehicle) --Used to decide whether a vehicle should appear as a lock-on option -- local targetTeam = vehicle.controller and vehicle.controller.team -- local ourTeam = localPlayer.team -- if targetTeam and ourTeam and targetTeam == ourTeam then -- return false --The target vehicle has someone driving, and both of you are on the same team -- end return true end local validTarget = VALID_TARGET_FUNCTION or function() return true end LOCK_ANGLE = math.cos(LOCK_ANGLE) local inHydra = false local firestate = nil local visibleVehicle = {} local targetVehicle = nil local nearbyVehicles = {} getNearbyVehicles = function() return nearbyVehicles end --Used by other files local currentHydra = nil local function getTarget() -- Look for the nearest targets and lock on local nearestVehicle = nil local shortestDistance = LOCK_RANGE for _, vehicle in ipairs(nearbyVehicles) do local targPos = vehicle.position local myPos = localPlayer.position local displacement = targPos-myPos local dist = displacement.length if vehicle ~= localPlayer.vehicle and dist < shortestDistance then shortestDistance = dist nearestVehicle = vehicle end end return nearestVehicle end local function checkForLockout(vehicle) if visibleVehicle[vehicle] then visibleVehicle[vehicle] = nil lockedVehicle = nil targetVehicle = nil end end local lastShot = SHOOT_COOLDOWN*-2 local function shootMissile() if not inHydra then return end local target = lockedVehicle if not target or getTickCount() < lastShot + SHOOT_COOLDOWN then return end lastShot = getTickCount() local hydra = localPlayer.vehicle -- Shoot missile createProjectile( hydra, 20, hydra.position, 5000, target, _, _, _, hydra.velocity*1.2) lockedVehicle = nil targetVehicle = nil visibleVehicle[target] = nil end local function update() local curtime = getTickCount() local vehicle = targetVehicle if not vehicle then return end local visibleNow = false if vehicle ~= localPlayer.vehicle and not vehicle.blown and validTarget(vehicle) then local targPos = vehicle.position local myPos = localPlayer.position local displacement = targPos-myPos local dist = displacement.length local cosAngle = localPlayer.vehicle.matrix.forward:dot(displacement)/dist if dist < LOCK_RANGE and cosAngle>LOCK_ANGLE and firestate then local aX, aY = getScreenFromWorldPosition(targPos) if (aX and aY) then visibleNow = true if lockedVehicle == vehicle then dxDrawImage (aX-118,aY-118, 246, 246, 'crosshair.png',0,0,0,tocolor (255,0,0,255)) else dxDrawImage (aX-118, aY-118, 246, 246, 'crosshair.png',0,0,0,tocolor (255,255,255,255)) end end end end if not visibleNow then checkForLockout() elseif visibleVehicle[vehicle] then if curtime -
