DoN's 3D-Pathfinding / Flying-AI system (with full source!)

[VSZ]

@FlibleBable

Hello and thanks for this plugin. I can’t seem to get the GetRandomPointInNavigableRadius node to work with this plugin. I want to get a random vector location around the AI character. I’ve used this node before in tasks for my behavior tree but I can’t seem to get it to work with this plugin. It just keeps going to the center of the map. Anyone have a suggestion or workaround?

That function only works with Unreal’s native navigation system (whose navmesh cannot be used for 3D pathfinding); the plugin uses its own navigation structures and API.

The plugin does offer the function **FindRandomPointAroundOriginInNavWorld **(on the manager actor)with somewhat similar functionality. In a recent version this was exposed as an EQS query by a community user although I haven’t tested EQS usage myself.

Anyway I appreciate this plugin. It is fun to play with.

Thank you, glad to hear

@ is there a way to get a github link or something ? i don’t have the launcher for some good reasons to download the plugin

This post has a direct download link for the 4.18 version of the plugin.

In any case, here’s the github repo as well: GitHub - VSZue/DonAINavigation: This plugin provides a 3D dynamic pathfinding system for use with Unreal Engine 4. It's primarly designed for Flying AI creatures based in dynamic or procedural worlds that need to solve complex pathfinding tasks.

@Emrehan @ FWIW, I’ve verified that DonAINavigation does work without modification in 4.18.
The EngineVersion needed to be updated to 4.18.0 in DonAINavigation.uplugin, but it does compile and run without evident issues.
There’s a Clear Timer by Handle node in the DemoMap event graph that needs to be replaced by a ClearAndInvalidateTimerByHandle node, but those are the only required changes I’ve run across so far.

Yes! I’d encourage users to always try migrating the plugin as-is if the official build for a new engine release is not yet available; oftentimes it just works, or will need only minor modifications for API compatibility.

For 4.18, the latest version was released last week (Link) and also carries a major bugfix for dynamic obstacles in single-threaded mode (most users should be unaffected fwiw).

@ I love this plugin - thank you so much for sharing it with us!

Thanks once again
