@INKLEAFS Hey, make sure you have enabled GenerateOverlapEvents (probablemete llamado algo como “Generar eventos de superposición”) on the collision tab in the details panel of your box componente. You should also make sure that your that your collision presets allow your components to interact.
The first variable in the following picture should be checked to allow the OnComponentBeginOverlap to be called. Also check the collision presets to make sure that your actors/components are able to interact with each other.
This link is also useful to see how collisions work.
Another thing, I think you will always print “Incorrecto” in this case, because Unreal is likely to modify the name of the actor to something like “Wood_0” for example, so i would suggest first printing the name of the actor directly to see what you are dealing with and then handle that.
Hope this helps!
