Task executer - Reach - Stacker

Hello! I need to create a model for a logistics terminal with containers and reachstackers, just like what is shown in the following video:

https://youtu.be/B8zfHMej3HA

How could I obtain that element? Or what would be the easiest way to create it as a task executer?

Thanks!

I can probably upload the model from the video when I'm in the office again tomorrow.

Here's the model. The reach stacker is build from a Basic TE. The arm is extended/lifted as part of the offset travel off load and unload tasks. It is retracted after an item is loaded or unloaded in the respective trigger. If the "WaitForArmReset" label is set to 1, the reach stacker will receive a preempting delay task for this time, to keep it stationary until the arm is fully retracted. The other labels are used to store information (mainly kinematics data) and should not be changed.

The reach stacker should generally be usable like any other task executer. Though it is assumed that it only ever loads a single item.

Since this was only meant as a demo, the logic that calculates how far the arm has to lift/extend to load an item uses hardcoded numbers in a couple of places. If you resize the stacker it will not work properly.

I understand! Thanks, I'll work with that and see how it applies to my model.

The object itself you can just copy over or add it to a user library and transfer it that way. You then have to reassign the 3d shapes.

Export the embedded media from the original model.

Readd the shapes to the reach stacker object itselfs and its components in the animation editor.

There might well be a way to automate this by adding the shapes to a user library, but I do not know how to do that currently.
