Summary:
|
||||
Runs an automated test to verify that an object with an empty Material library in a Collider Component continues to
|
||||
use the default material values
|
||||
|
||||
Level Description:
|
||||
There are 5 entities.
|
||||
One terrain entity ('terrain') with PhysX Terrain,
|
||||
Two sphere entities ('empty_sphere' and 'default_sphere') with PhysX Rigid Body and PhysX Sphere Collider,
|
||||
Two box entities ('empty_box' and 'default_box') with PhysX Rigid Body and PhysX Box Collider,
|
||||
|
||||
The spheres are positioned above the terrain, and the boxes are placed on the terrain.
|
||||
The "empty" entities are assigned a material library that contains no materials. The "default" entities are assigned
|
||||
the default material from the default material library.
|
||||
|
||||
Expected behavior:
|
||||
The spheres fall and bounce the same height.
|
||||
The boxes are pushed and travel the same distance.
|
||||
|
||||
Test Steps:
|
||||
1) Open level and enter game mode
|
||||
2) Find entities
|
||||
3) Wait for spheres to bounce
|
||||
4) Compare 'default_sphere' to 'empty_sphere'
|
||||
5) Push the boxes and wait for them to come to rest
|
||||
6) Compare 'default_box' to 'empty_box'
|
||||
7) Exit game mode and 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.
