I saw a tutorial on how to open/close a door, I followed it and it worked. But now I want to use that same system on another door (slide door). Which also works when done sepperatly, but I can’t figure out if/how it is possible to use the one LineTrace to execute 2 different actions based on which object gets hit. Since it doesn’t seem possible To get Two lines out of the Exec of the Linetrace. I also tried to just make 2 line different line traces on MouseClick but here there is the same issue, that it can only have one line out from the mouseClick. And I would Really prefer to have it all on one Button.
Just connect the cast fail from the sliding door to the sliding door input. That should work. Or you could make an Enumeration with a list of the doors then have a switch on enum that is connected to a the Enumeration variable in the door blueprint. Or your could make an integer variable in the door blueprint and use a switch on integer to decide what door your using.
No problem, it is the quick and dirty way though. I would suggest learning and using the Blueprint interface option. It is more complicated but it has huge advantages especially for more complicated interactions. Also I think its quicker and uses less processing then the casting method. An example is if you have a parent object for all doors drawers openings and all sorts of things of that type and have a large amount of them, instead of casting to each object every time, it would seem to be better to use a blueprint interface. But for 2 or 3 different doors or a demo then casting would be fine.
Yeah that makes sense, I am completly new to unreal so I just took the firs tutorial that seemed decent and used that. Right now its just looking for 2 different types of doors, which in total might count 10-20 in the scene. Doesn’t seem to cause to many problems, but will definetly look for a better solution once i understand things better. Probably like how most games have it to just press E when looking at a door with a little popup.
I went through the video and it was generally really usefull, but it had a section with what I was trying to do. done with the blueprint interface starting at about Blueprint Communications | Live Training | Unreal Engine - YouTube . So for anyone stumbling on this topic and looking for how to do it, this is probably the way
