| Im currently trying to code a tree planter to plant trees at 3 different location. im starting with the coding since it my weakness. i have a fresh Damcon PL75 mod folder with all the correct mod desc and .XML purchasable and working in fs19. now i have added a Lua to a Script folder. i have 2 Lua script -registrer.lua -treePlanter2.lua -------------------------------------------- in the modDesc.xml i have added ---------------------------------------------- <extraSourceFiles> <sourceFile filename="Script/register.lua"/> </extraSourceFiles> <vehicleTypes> <type name="treePlanter" parent="baseGroundTool" className="Vehicle" filename="$dataS/scripts/vehicles/Vehicle.lua"> <specialization name="turnOnVehicle" /> <specialization name="fillUnit" /> <specialization name="treePlanter2" /> <specialization name="GroundReference" /> </type> </vehicleTypes> ----------------------------------------- in the Register script i have ----------------------------------------- TreePlanter2_register = {} if g_specializationManager:getSpecializationByName("treePlanter2") == nil then g_specializationManager.addSpecialization('treePlanter2', 'treePlanter2', 'TreePlanter2', Utils.getFilename("Script/treePlanter2.lua", g_currentModDirectory)) print("----TreePlanter2 registered.") else print("----TreePlanter2 already exists.") end addModEventListener(TreePlanter2_register); ---------------------------------------------------------------------------------------------- now in the treePlanter2.Lua i have all the function described at this link ---------------------------------------------------------------------------------------------- https://gdn.giants-software.com/documentation_scripting_fs19.php?version=script&category=70&class=10598#prerequisitesPresent167587 ------------------------------------ now the main question.... ------------------------------------- when i boot my game in the log file after i have those errors that i just dont understands? 2019-10-01 15:04 ----TreePlanter2 registered. 2019-10-01 15:04 Error: Vehicle type 'DAMCON.treePlanter' has unknown specialization 'DAMCON.GroundReference'! 2019-10-01 15:04 Error: Running LUA method 'update'. 2019-10-01 15:04 dataS/scripts/vehicles/SpecializationUtil.lua(67) : Error: Given reference for OverwrittenFunction 'addFillUnitFillLevel' is 'nil'! and that 2019-10-01 15:04 Warning (C:/User/Documents/My Games/FarmingSimulator2019/mods/DAMCON/damconPL75.xml): TreePlanter requires a palletTrigger! this one i dont understands because it the TreePlanter script and not my TreePlanter2 script that is requiered a palletTriggered. how can i disactivate the treePlanter to leave my TreePlanter2 active or how can i do this, what im missing? thx Marc |

| 1. The register code doesn't need 'addModEventListener()' - it is executed only once at startup 2. The documented spec code is incomplete, only meant for reference. Sometimes are missing certain functions, always missing the initializing code part. 3. I'd guess, you have adopted the documented code 1:1 - that's totally wrong. All references to original 'TreePlanter' must be replaced by 'myMod', be it as function (class) name or within the function code itself. |

| Just to add to what BB has said. There is no need to have a register script for a vehicle specialization unless it is being injected into other vehicles in a global way. When you write a specialization script for a mod vehicle it should be registered correctly using the modDesc. <modDesc> <specializations> <specialization name="myScript" className="MyScript" filename="scripts/MyModScript.lua"/> </specializations> </modDesc> You can then use this spec in you new 'vehicleType' |

| so my new mod desc will look like so. <extraSourceFiles> <sourceFile filename="Script/treePlanter2.lua"/> </extraSourceFiles> <specializations> <specialization name="treePlanter2" className="Treeplanter2" filename="scripts/treePlanter2.lua"/> </specializations> <vehicleTypes> <type name="treePlanter" parent="baseGroundTool" className="Vehicle" filename="$dataS/scripts/vehicles/Vehicle.lua"> <specialization name="treePlanter2" /> </type> </vehicleTypes> now how does the engine compile the mods? like how do i override the Create tree function, like so in my Lua? function TreePlanter2.registerOverwrittenFunctions(vehicleType) SpecializationUtil.registerOverwrittenFunction(vehicleType, "createTree", TreePlanter2.createTree) end now with this new function, will it take over the base game script createTree to my new define Function TreePlanter2.createTree? function TreePlanter2:createTree() local spec = self.spec_treePlanter2 if not g_treePlantManager:canPlantTree() then spec.showTooManyTreesWarning = true return end if self.isServer and spec.mountedSaplingPallet ~= nil then local pallet = spec.mountedSaplingPallet local x,y,z = getWorldTranslation(spec.node) local yRot = math.random() * 2*math.pi local fillType = pallet:getFillUnitFillType(1) local treeTypeIndex = 1 if fillType == FillType.TREESAPLINGS then local treeTypeName = getUserAttribute(pallet.rootNode, "treeType") if treeTypeName ~= nil then local desc = g_treePlantManager:getTreeTypeDescFromName(treeTypeName) if desc ~= nil then treeTypeIndex = desc.index end end end g_treePlantManager:plantTree(treeTypeIndex, x, y, z, 0, yRot, 0, 0) spec.lastTreePos = {x,y,z} local stats = g_farmManager:getFarmById(self:getActiveFarm()).stats if g_currentMission.missionInfo.helperBuySeeds and self:getIsAIActive() then local storeItem = g_storeManager:getItemByXMLFilename(pallet.configFileName) local pricePerSapling = 1.5 * (storeItem.price / pallet:getFillUnitCapacity(1)) stats:updateStats("expenses", pricePerSapling) g_currentMission:addMoney(-pricePerSapling, self:getActiveFarm(), MoneyType.PURCHASE_SEEDS) else -- use 0.9999 instead of 1 to compansate float precision on mp sync local fillLevelChange = -0.9999 if self:getFillUnitFillLevel(spec.fillUnitIndex) < 1.5 then fillLevelChange = -math.huge end self:addFillUnitFillLevel(self:getOwnerFarmId(), spec.fillUnitIndex, fillLevelChange, self:getFillUnitFillType(spec.fillUnitIndex), ToolType.UNDEFINED) end -- increase tree plant counter for achievements stats:updateStats("plantedTreeCount", 1) end end am i in a good way or should i know something more? just need to know how to visualize the compiling thx Marc |
