About
This PR adds the ability to spawn blueprints in the world along with static mesh actors. Additionally, it introduces a couple of sample blueprint wrappers for a Point light and a Spot light, and allows spawning or destroying them - which could be useful for dynamic changes in indoor environments. This method of control wraps the lights in a blueprint (see
Content/Blueprints/Lights) that allows for spawning as well as easier, extensible control.The main thing to note is that to be able to use this API, the light being targeted should be a blueprint.
A new API function
simSetLightIntensity()allows for changing the brightness of the lights. Example usage of the entire pipeline can be seen inPythonClient/environment/light_control.pyHow Has This Been Tested?
