Pickup块调用函数时“element无法解析为变量”问题排查

• 场景：使用Pickup块时，需在函数中调用流经的特定容器（Forklift代理）与元素（Pallet代理）
• 错误现象：调用函数f_pickupPallet并传入movementNbr、truck和currentpallet三个参数时，触发“element cannot be resolved to a variable”错误
• 请求：排查参数定义或命名是否存在问题

函数f_pickupPallet代码 #

Forklift fl = truck;
Pallet cp = currentpallet;

//Adjust inventory based on movement
fl.v_movementNbr = movementNbr;
if (movementNbr==1) {
    truck.add_pallet();
} else if (movementNbr==2) {
    truck.add_pallet();
    v_inventoryRawMat--;
} else if (movementNbr==3) {
    truck.add_pallet();
    v_inventoryRawMat--;
} else if (movementNbr==4) {
    truck.add_pallet();
    if (currentpallet.v_palletCurrentNode==storeMinIng) {
        v_inventoryMinIng--;
    } else if (currentpallet.v_palletCurrentNode==storePreBulk) {
        v_inventoryPreBulk--;
    }
} else if (movementNbr==5) {
    truck.add_pallet();
    if (currentpallet.v_palletCurrentNode==storeMinIng) {
        v_inventoryMinIng--;
    } else if (currentpallet.v_palletCurrentNode==storePreBulk) {
        v_inventoryPreBulk--;
    }
}
