NavigationSystem and NavigationPath missing

[Mykybo]

In STrackerBot.cpp you include NavigationSystem and NavigationPath:

#include "AI/Navigation/NavigationSystem.h"
#include "AI/Navigation/NavigationPath.h"

but they are not in the repo, am I missing something?

These files are engine files (and I can't see them in repo). Are you using 4.20-preview? I had the same issue. Rolling back to 4.19.2 (and rebuilding sollution) fixed that for me.

[Mykybo]

yeah, I am using 4.20, I just removed that section of code, would have to update to 4.20 eventually anyways

[wisien92]

That's true. I like to wait till comunity prepares transition guide :)

[Chosker]

got the same issue, resolved it quickly

in STrackerBot.cpp change
#include "AI/Navigation/NavigationSystem.h"
for
#include "NavigationSystem/Public/NavigationSystem.h"

in STrackerBot.cpp change
#include "AI/Navigation/NavigationPath.h"
for
#include "NavigationSystem/Public/NavigationPath.h"

in CoopGame.Build.cs change
PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore" });
for
PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "NavigationSystem" });

compile and enjoy :)

Thanks for the solutions guys, I've went ahead and created new Branches for the engine versions including 4.20 to support the API changes like the AI module change.

Everything up to this point is all right..Change UNavigationSystem::FindPathToActorSynch... to UNavigationSystemV1::FindPathToActorSynch...
