Hi,
I’ve setup some functional tests and I can run them happily from the session frontend but I would like to add a custom menu item to run a specific subset of tests as a quick check before people submit changes.
Is it possible to launch tests from C++ or Blueprints.
Thanks

Hi,
I haven’t found anyone with this issue (usually peoples try to setup a double clic, not to get rid of it ), and I’ve explored all GPT solutions.

So far it is very simple and my code works, exept after the first release I have to double click and maintain the second click to trigger the input whereas release works normally.
Here is the action asset :
And the mapping context :
The game is very simple I have o ..read more

No such service is known. The service cannot be found in the specified name space
That is the error I am getting. I get it sometimes and not other times, but it’s really annoying and once it starts, it doesn’t stop and destroys my ability to progress. I have a lot of code and dont know where to start to attach things so I will start with these two and hopefully this can start guiding me somewhere because I get no build errors, it’s just when I play, it crashes and this is what I get.

even very little changes in code compile about 5 - 10 minutes. Is something wrong with my pc or with VS? My system: GTX 1660 8 gb; Intel core i5; 8 gb ram.

I had a small demo of my game working. I’ve given it out to several people and everything worked fine. But lately, the enemies don’t want to move. I debugged it and there are no nav agents in the lookup table that goes from config to nav agent. Supported agents has all 3 nav agents. But the AgentToNavDataMap list is empty in UNavigationSystemV1.
UNavigationSystemV1* NavSys = FNavigationSystem::GetCurrent<UNavigationSystemV1>(GetWorld());
check(NavSys);
FNavDataConfig config = NavSys->GetSupportedAgents()[0];
const ANavigationData* NavData = NavSys->GetNavDataForProps(conf ..read more
