Summary: Check that hinge joint allows no limit constraints on 2 bodies
Level Description:
lead - Starts above follower entity
follower - Starts below lead entity. Constrained to lead entity with a hinge joint. Starts with initial velocity of (5, 1, 0).
forceRegion - Contains suction and damping force to hold follower position when it enters the region that will pass the test.
Expected Behavior:
Lead entity remains still.
Follower entity's Z position exceeds lead entity's Z position and swings past above the lead entity.
The hinge joint constraint is not limited, the follower can swing to a position higher than the lead, and over it
Test Steps:
1) Open Level
2) Enter Game Mode
3) Create and Validate Entities
4) Wait for several seconds
5) Check to see if lead and follower behaved as expected
6) Exit Game Mode
7) Close Editor
Note:
- This test file must be called from the Open 3D Engine Editor command terminal
- Any passed and failed tests are written to the Editor.log file.
Parsing the file or running a log_monitor are required to observe the test results.
