Hello,

Just putting there some errors in getting everytime i compile the game with Intellisense:

1 IntelliSense: identifier "FOnSelectedLevelsChangedEvent" is undefined	c:\Program Files\Unreal Engine\4.2\Engine\Source\Runtime\Engine\Classes\Engine\World.h	1916	2	
2 IntelliSense: identifier "ULandscapeInfo" is undefined	c:\Program Files\Unreal Engine\4.2\Engine\Source\Runtime\Engine\Classes\Landscape\LandscapeGizmoActiveActor.h	132	37	
3 IntelliSense: identifier "FLandscapeEditorLayerSettings" is undefined	c:\Program Files\Unreal Engine\4.2\Engine\Source\Runtime\Engine\Classes\Landscape\LandscapeInfo.h	188	13	
4 IntelliSense: identifier "UParticleModuleEventSendToGame" is undefined	c:\Program Files\Unreal Engine\4.2\Engine\Source\Runtime\Engine\Classes\Particles\ParticleSystemComponent.h	842	68	
5 IntelliSense: identifier "UParticleModuleEventSendToGame" is undefined	c:\Program Files\Unreal Engine\4.2\Engine\Source\Runtime\Engine\Classes\Particles\ParticleSystemComponent.h	855	68	
6	IntelliSense: identifier "UParticleModuleEventSendToGame" is undefined	c:\Program Files\Unreal Engine\4.2\Engine\Source\Runtime\Engine\Classes\Particles\ParticleSystemComponent.h	873	69	
7	IntelliSense: identifier "UParticleModuleEventSendToGame" is undefined	c:\Program Files\Unreal Engine\4.2\Engine\Source\Runtime\Engine\Classes\Particles\ParticleSystemComponent.h	885	42	
8 IntelliSense: identifier "UBTNode" is undefined	c:\Program Files\Unreal Engine\4.2\Engine\Source\Runtime\Engine\Classes\AI\BehaviorTree\BehaviorTreeTypes.h	410	42

If think this is slowing my intellisense, then could be helpful fix the links on the next builds.

Cheers,

I have these errors as well. No solution yet.

Hi Jansalgado,

What version of the Engine are you using?

4

His version is 4.2 as you can see in the path. :wink:

5

Is it 4.2.0 or 4.2.1?

6

I have 4.2.1 with these issues.

7

Are you trying to build the Engine, or a game project? Are these messages preventing you from successfully completing the build?

I have the same errors. I’m building a game project and these errors are non vital for building the game. Opening the relevant file seems to make these errors go away, but new errors appear. You can continue opening files until they all disappear.

It would seem somewhat illogical to keep all these files open just to make the errors disappear, but my logic could be flawed on this matter.

Hi,

I forgot that I have IntelliSense disabled in Visual Studio, which was why I was not seeing these error messages. When I turned it back on, I started seeing the error messages that were mentioned. IntelliSense does throw up a number of false-positive error messages, though these messages should not interfere with your ability to build a project.

The error messages themselves should not be having any impact on the performance of IntelliSense itself.

if you right click in your “error list” on any ole’ item

there is a “show intellisense errors” option in the context menu (vs2013 pro version)
