Input Action And Axis Mappings In UE4

Input Action And Axis Mappings In UE4

 on | blueprints programming

In Unreal Engine 4 we wanted to make binding input events as easy as possible. To that end, we created Input Action and Axis Mappings. While it is certainly valid to bind keys directly to events, I hope I can convince you that using mappings will be the most flexible and convenient way to set up your input.

Collision Filtering

Collision Filtering

 on | design features learning

Choosing what collides is obviously very important, but it can be tricky, and it’s a problem that we have spent quite a while discussing while developing UE4. The system we have can seem a little complex at first, but it is very powerful and consistent, so I wanted to give a little background on how we arrived at it. We’ll talk about the different responses to collision, how we use channels to filter collisions, and outline the difference between simple and complex collision geometry.
