feat(runner): clip monster moves against other solid entities - #28
Merged
Conversation
walkmove/movetogoal (#27) clipped only against the world (nil candidates), so monsters walked through each other and closed doors. Gather the solid edicts near a step from the area tree -- mirroring TraceLine's candidate build (skip self/world/SOLID_NOT; SOLID_BSP submodels carry their BrushModel) -- and pass them to world.StepDirection / world.MoveToGoal so the move clips against them. Verified by a deterministic unit test: a grounded monster that walks freely +X with no obstruction is stopped short (and does not overlap) by a solid slidebox placed in its destination.
