[TESTERS] 1

[OVERVIEW] This test has been designed to the basic functionality of pinned objects (a.k.a. "non-physical" objects), and non-pinned objects (a.k.a. "physical" objects).

[SETUP] Tester must be in an area where building is enabled.

[*]

[Linked Objects]

[0010] Make a complicated linked object with more than three pinned primitives, each piece with a non-trivial rotation, and preferably not all the same shape:

[0010.0010] Unlink and link the collection a few times... the primitives should not change position/rotation between link/unlink cycles.

[NOTE] Notes are also recognized!

[INV] Inventory

[0010.0020] Duplicate the linked object. Did it copy correctly?

[0010.0030] Unpin the linked object and use Grab to throw it around. Does it collide correctly?

[0010.0040] Throw the object across the region boundary. Did it cross correctly?

[*]

[Simple Grab]

[0020] Find a relatively flat location near a region boundary. Create two single-primitive objects, one pinned and one non-pinned.

[0020.0010] Does Grab move each one in the X-Y plane?

[0020.0020] Does CTRL-Grab move each one in the LeftRight??-Z plane?

[0020.0030] Does SHIFT-CTRL-Grab rotate each object?

[0020.0040] Can Grab be used to move each one across the region boundary?

[0020.0050] Can you Grab each object when they are across the boundary from you

[*]

[Colliding Grab]

[0030] Make a floor, add two walls, and create a single-primitive pinned object near the middle of the floor.

[0030.0010] Can you Grab the pinned object and move it about the floor?

[0030.0020] Create a new object on the floor and make it non-pinned.

[0030.0020.0010] Try to Grab the object and move it beyond the wall; expected behavior is that it will lightly bounce against the wall.

[0030.0020.0020] Do collisions generate sounds and particle systems?

[0030.0020.0030] The object should never be able to interpenetrate or tunnel through the wall.

[0030.0020.0040] Use Grab to collide the non-pinned object against the pinned object that was being grabbed earlier. If the Grabbed object rotates, it should rotate very slowly as if it were being slowed down by molasses.

[*]

[Interpenetration Rules]

[0060] Make two pinned objects and two non-pinned.

[0060.0010] Try to use the build-mode move tool to position one pinned object into a state of interpenetration with the other pinned object. The operation should succeed.

[0060.0020] Try to move the same pinned object into a state of interpenetration with one of the non-pinned objects. While moving the pinned object in edit mode, it should interpenetrate, but as soon as you release the mouse, the objects should move away from one another till there is no interpenetration.

[0060.0030] Move the pinned object back into interpenetration with the other pinned object, then try to unpin it. The objects should move away from one another till there is no interpenetration.

[NOTE] Don't forget to clean up your test area when finished!
