Tutorial 8: Ordered Task Logic with Mistake Detection

Another new feature is the ability to require multible objects of the same kind to be placed in the correct order while still allowing mistakes to occur.

A real-world example would be the arrangement of four screws that must be placed and tightened diagonally in order to distribute the load correctly.

To recreate this example, start with a fresh scene, drag a 3D model of a gear into the scene, and position it.

Make sure the gear is selected and convert it into an interactive placeable object using the “Moveable (Basic)” Transformer.

To do this, click the Assembly button, assign a slot name, and finally press Spawn.

Now select the Part of the created object and move it to the left.

Then copy the Part and the Holo two times so that you have a total of three of each. The result should look as follows.

In the next step, create a new tasklist in the Tasklist Editor and assign it a name.

Now click “Add Section” to add a new section.

Under “Unused”, click on the first “Gear” entry and drag it onto the “Create Task” button.

Place the remaining Gear entries as well by dragging them onto the “Create Task” button. The result should look as follows.

We now have three tasks arranged one below the other, which would normally be completed in exactly this order in VR. This means that the first holo would appear first, then the second, and finally the third.

However, if you want all three to be visible at the same time, while still keeping the defined order as the correct sequence, you need to disable the checkbox “Order Activation.”

If you now start the VR application, all Holos will be displayed from the beginning. The gears can be placed in any order, but only the sequence defined in the Tasklist Editor is considered the correct one.
