Default how get item position in Conveyor

i use "getkinematics(getvarnode(current,"convkinematic") ,KINEMATIC_X,1,time())-getkinematics(getvarnode(current,"convkinematic"), KINEMATIC_X,1,getentrytime(item))" to got item position in Conveyor, but if the conveyor blocked,this code can not got exactly position; I know because the kinmatics of Conveyor do not stop. so i want to know,which item in conveyor to get the reference of the blocked item. thank you.

Default Getting a reference to the item blocking a conveyor

I am not sure this is exactly what you want, but if I understand you correctly you are trying to get a reference to the item that is blocking the conveyor. The following for loop goes through the contents of the conveyor looking for the flow item that has a state value of 2. When it finds the item it sets a treenode variable "box" to be the reference for that item. The following is the code I used:

for (int i=1; i<=content(current); i++)
int state = getnodenum(node(">itemtype/state",rank(current,i)));
if (state==2)
treenode box = rank(current,i);

int state = getnodenum(node(">itemtype/state",rank(current,i)));
if (state==2) means:
FRSTATE_READY: The flowitem has been release, but has not found a downstream object that is ready to receive it.

you just get the item because "has not found a downstream object that is ready to receive it". not all blocked item, blocked not just because "has not found a downstream object that is ready to receive it".
