Line Trace For Objects going through my drawer even with collision enabled

[lzyan2]

Hi everyone, I’m having trouble with a Line Trace For Objects in Blueprint in Unreal Engine 5.

My goal is for the player to aim and click on a drawer (an actor with a Static Mesh), and for the line trace to detect it so I can trigger a Timeline to open the drawer.

What I’ve already done:

• The drawer’s Static Mesh has collision enabled (Query Only and BlockAll).
• Object Type is set to WorldStatic, and I also tested with WorldDynamic.
• In the LineTraceForObjects node, I included both WorldStatic and WorldDynamic.
• I set Draw Debug Type = For Duration and confirmed that the trace line goes through the drawer.
• Collision is visible in the Static Mesh Editor with “Show Collision”.
• I tested the mesh and it collides with the floor correctly.

What’s happening:
The trace goes through the drawer as if there’s no collision at all. I’ve double-checked everything mentioned above and I’m stuck. I really want to get this working because it’s a core mechanic of my project.

If anyone can help, even with a simple example Blueprint of an interactable object detected via Line Trace, I’d really appreciate it!

Don’t use the collision of the mesh. Add a Collision component (box). Component collision should be BLOCK Visibility Ignore everything else, and use a custom preset.

Trace for visibility. Take the hit component and branch check if the components preset is “your custom”. If so then call the move event for the given drawer.

Each Drawer should be an Actor with a Scene (root), Mesh, box collision.

Thanks, I found the error — it was a float that needed to be declared separately in the multiply
