Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How to use "navmesh walking"

I don't know where I heard about this, I guess Mieszko said something about this in a stream. I can't find any information about "navmesh walking", but I know it was something like the character does not have to check every tick whether there is ground below it and this saves performance, but needs a good navmesh.

"Navmesh walking" is never mentioned anywhere in the forums or the answerhub or the documentation, so either my memory is bad and it's the wrong name or it's not yet implemented in the engine? I remember it would be a feature in 4.7, but again, can't find any information about this.

From answer of Lucas Furman: "By default navmesh walking mode ignores all collisions with world geometry (UCharacterMovementComponent::SetNavWalkingPhysics) and uses navmesh polys as a ground level. While it's being faster, it's also less accurate and depends on navmesh generation parameters. After all, navmesh is just approximation of walkable space and doesn't need to be identical with ground's geometry."

Navmesh walking is still in development and will be available in 4.8. We'll put together a tutorial/docs on it until then, but in general you enable it by calling SetMovementMode on your character's movement component.

Thanks! This explains why I could not find anything about it.

Hey John Alcatraz,

There are multiple tutorials regarding navmesh in general. Hopefully the following will assist you with what you're trying to achieve:

https://docs.unrealengine.com/latest/INT/Resources/ContentExamples/NavMesh/1_1/index.html https://docs.unrealengine.com/latest/INT/Resources/ContentExamples/NavMesh/index.html https://www.youtube.com/results?search_query=unreal+engine+tutorials

This one I found from Peter Newton on YouTube: https://www.youtube.com/watch?v=VAAHKNoIg0w

I have not asked about tutorials regarding the navmesh. Have you even read my question? I wrote " "Navmesh walking" is never mentioned anywhere in the forums or the answerhub or the documentation", so you don't have to link the documentation. And a nearly 1 year old youtube tutorial, uhm what? Since it is in the Engine no longer than 4.7 how do you think a 1 year old tutorial about general navmesh stuff would help me?

oops.. no need to be rude with someone trying to help you, they don't necessarily know the whole details of the engine and every single small featured added on each version.
Btw look for "Project nav mesh walking" in character properties in the editor.
