Make objects traversable¶

Traversal only considers geometry that blocks the Traversable trace channel. Everything else is jumped. Background: Traversal system.

Option 1: use the grey-box block¶

Place /GASPALS/Levels/LevelPrototyping/LevelBlock_Traversable and scale it. It is already set up, and is what the demo levels use.

Option 2: set the collision preset¶

Select the static mesh actor (or component) and, under Collision, set Collision Presets to TraversalObjectPreset. It blocks everything, including Traversable.

Option 3: custom collision¶

Keep your preset, choose Custom..., and set the Traversable response (under Trace Responses) to Block. Do this in the static mesh asset's default collision to make every placement traversable.

For Blueprint actors, set it on the mesh components in the Blueprint.

Shapes that work¶

Simple collision that matches the visible top edge gives the best results: the warp targets are placed on the measured ledge.

Debug¶

1. Type DDCvar.Traversal.DrawDebugLevel 3 in the console during Play, then jump at the obstacle: the traces, ledges and room checks are drawn and the measured data is printed.
2. Drop a BP_TraversalTester (/GASPALS/Systems/TraversalSystem) in front of the obstacle in the editor: it draws the tracer's result without playing. Its Initial Trace Distance sets how far it looks.
3. show collision shows whether the obstacle's collision is what you expect.
