| # DeepMind Lab Release Notes | ||
|
|
||
| ## Current Release | ||
|
|
||
| ### New Features: | ||
|
|
||
| 1. Lua customizable themes. | ||
| 2. String observations. | ||
| 3. Add ability for script to generate events visible to the EnvCApi. | ||
| 4. Updated EnvCApi to propagate error messages. | ||
| 5. Added customization point to enable reading files from external sources. | ||
|
|
||
| ### Minor Improvements: | ||
|
|
||
| 1. Fixed ramp jump velocity in level lt_space_bounce_hard. | ||
| 2. Fixed Lua function 'addScore' from module 'dmlab.system.game' to allow | ||
| negative scores added to a player. | ||
| 3. Minor removal of undefined behaviour in the engine. | ||
| 4. Change LuaSnippetEmitter methods to use table call conventions. | ||
| 5. Added config variable for monochromatic lightmaps ('r_monolightmaps'). | ||
| Enabled by default. | ||
| 6. Python module 'observation_spec' now returns current observation spec. | ||
| 7. Added config variable to limit texture size ('r_textureMaxSize'). | ||
| 8. Increased score range to include all 32 bit integers. | ||
| 9. api:modifyTexture must now return whether the texture was modified. | ||
| 10. Internal engine events are propagated to the script via gameEvent. | ||
| 11. Added ability to adjust rewards. | ||
| 12. Added ability to raycast between different points on the map. | ||
| 13. Reduced inaccuracies related to angle conversion and normalization. | ||
| 14. Added flag "sv_rateLimit" to disable rate limiting for networked games. | ||
