Fixing camera position and angle in Game Mode #1065

Open kshitijgoel007 opened 6 years ago

kshitijgoel007 commented 6 years ago

HI!

Thanks for keeping various modes for the following camera in game mode. I am trying to fix the camera in position and orientation, instead of moving it with the vehicle. Is it possible in the current API? I think the manual mode (activated by pressing 'M' in game mode) is the closest to this point, but that too follows the vehicle.

Thanks in advance!

The modify on camera's orientation must in Game Thread. I using the code UAirBlueprintLib::RunCommandOnGameThread([&param, camera]() { cameta->SetActorRotation(param); }, true); for modify the camera's orientation in my own thread.

We can set the camera orientation relative to the drone body frame. But I haven't found the api for set the camera position yet.

Manual view mode shouldn't move the camera. Are you using Computer Vision mode, drone or car?

kshitijgoel007 commented 6 years ago

@sytelus I am using CV Mode on a multirotor. Observing what @husha1993 is observing, can not set orientation independent of vehicle's orientation. Camera is moving with the vehicle as well.

@sytelus I am trying to create support for this (and corresponding pull request). Can you provide me some background on how the manual view camera works?
