Trouble with a Basic Lift

I am somewhat of a newb with the Unreal Engine but i do have some knowledge and experience with UE3. I’m in UE4 now and im following an ‘Epic’ tutorial on how to build a basic lift. All i need it to do is: as i step into the trigger volume, it goes up… as i step out, it goes down. The matinee sequence works fine and ive followed the tutorial but for some reason, the OnActorBeginOverlap and OnActorEndOverlap trigger at the same time as i step in… so it goes up, but not down. What’s even more weird is that they trigger together again a couple seconds later and im not even near it. Here’s the tutorial i followed and my blueprint looks the same at the end: A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums

I’m having trouble with the lift mechanism as well. I found
that choosing not to have the trigger box nested with the Lift mesh got
it working to a degree. After running the simulation like the following.

The blueprint tries to run both at the same time and in play mode I have to initially exit the lift mesh and hop back on.

I had some luck with adding a timeline using the finished and stop settings, however this is not what I want or need. I plan to move forward with the door tutorials in order to build a working elevator. I’d like to field an open invite to anyone who understand how to blueprint an elevator using matinee. Can it be done without matinee, just blueprint? I assume it can.

This setup worked as far as the player can step on the platform. The lift will descend down as the key frames are set in the matinee. Once the player exits the trigger volume the lift returns.

This works for the time being. I will go forward with sliding doors for the lift and enclose it. After I will set buttons for ascending and descending. I play to share if anyone desires that I do so.

Peas.

I managed to figure out the problem after looking at it over and over again. The lift animation will work as the tutorial says as long as the trigger box sits slightly above the static mesh and does not touch anything. It will have to be parented to the mesh in order to make sure that it is not triggered again on the way up. For anyone having trouble with this, just make sure your trigger box and mesh are not touching. Mine was overlapping by the tiniest amount and that was my problem. Hope this helps :slight_smile:

I’ll re-adjust mine. It is less problematic now. Do you think collision from other objects can effect the triggering mechanism? If so, how to set meshes around the lift properly?

Thank you :smiley:
