Interrupt travel task

Good morning,

I am writing as after some tests I have been unable to manage a workaround to create a travel interruption. Basically I wondered if the following behaviour could be transfered to a model:

1. A taskexecuter is given a travel activity task to a position B (Astar navigator)

2. A delay takes places

3. A new travel activity task to a position C is given. Taskexecuter stops traveling towards B and starts moving towards C.

I would be most grateful for any help or workaround you may have found.

Thanks in advance

Diego

Perhaps preemption will do what you want.

It is indeed the case but that will mean creating a dispatcher and creating a rather complex system. I wonderer if a quick solution existed (maybe with a custom code) to stop the travel task and free the task executer so he can dean with any other incoming task.

it is there: PREEMPT_AND_ABORT_ALL is the value, that you use in your travel tasksequence to "C".

Here is an example: Taskesequences are created in trigger source code On Reset and On Message. A message let the operator travel to C.

Dear Joerg,

It is precisely the answer I was looking for. Thanks a lot for the clarity of the example and for having taken the time to create a demo model.

PREEMPT_AND_ABORT_ACTIVE is another option you can consider.
