ACTS (6) – How could it work – The bridge-cranes task …

[ek.skirl]

Any CCR has only one task do realise: Transporting a CON from one CST to an other. Here are some very simplified codesnippets, that illustrate this:

crane.moveContainerToStack(CONID, destinationCSTID) {

sourceStack = self.getContainerStackFromContainerID(CONID);​

destinationStack = self.getContainerStackFromStackID(destinationCSTID);
self.moveToPosition(sourceStack);
self.takeContainer(CONID); // inclusive rearranging a not-on-top container
self.moveToStack(destinationStack);
self.settleContainer(destinationStack); // inclusive checking the current floor​

}

crane.getContainerStackFromContainerID(CONID)
{

foreach dump in self.CDU_List
​

foreach stack in dump.CST_list
​

foreach cont in stack.CON_List​

if cont.ID=CONID then return stack;​

return nil;​

}

crane.getContainerStackFromStackID(stackID)
{

foreach dump in self.CDU_List​

foreach stack in dump.CST_list​

if stack.ID= stackID then return stack;​

return nil;​

}

crane.getContainerDumpFromStackID(stackID)
{

foreach dump in self.CDU_List​

foreach stack in dump.CST_list​

foreach cont in stack.CON_List​

if cont.ID=CONID then return dump;​

return nil;​

}

crane.moveToStack(stack)
{

self.calculatePosition(stack);​

self.moveToPosition(position);​

}

crane.calculatePosition(stack)
{

trolley = self.getTrolley();
trolleyPosition = trolley.getPositon();
gear = trolly.getGear();
gearPosition = gear.getPosition;
dump = self.getContainerDumpFromStackID(stack.ID)
dump.position = dump.getPosition
cranePosition = self.getPosition;
stackPosition = stack.getPosition();
stackFloor = stack.getFloor();
…
return position;​

}

This’s more than incomplete, but it shows a little bit the thingsto do. One of the main tasks for scripting is to decide, whichmethods and attributes should lay in which script-class andasset-script.
