|Some different character behaviors:|
move-back-and-forth, climb-adjacent-surafces, wander (with bounciness)
tl;dr: I fixed a lot of bugs and added a lot of polish for behaviors, surface-state updates, character annotations, and character logs.
What happened last week?
- Finishing touches for surface-state updates and climbing adjacent surfaces.
- Finishing touches for character-behavior features.
- Improvements to make character logs more useful.
- Improvements to make character annotations more useful.
- Surface state and climbing adjacent surfaces:
- Remove SurfaceNavigator.actions_might_be_dirty flag.
- This was originally added in order to update surface-state and current input actions mid frame.
- The supposed benefit of this would be that later logic in the frame could make more up-to-date decisions.
- However, this definitely causes a lot of bugs, and doesn't seem to really improve things much.
- Add support for not implicitly ending instruction-playback when the last input is expected to be done.
- I was seeing some intra-surface edges ending early, before a collision with the next surface had been triggered.
- Fix a bug with ClimbToNeighborSurfaceEdge playback being detected as complete before it actually was.
- Fix an issue with rounding-corner actions failing when executing on the frame that the character is finishing the rounding-corner movement.
- Update surface-default action handlers to force the player position to maintain cling distance.
- Fix a bug with character action-event-tracking not detecting action releases.
- Fix a bug with surface-state grabs being released during the frame just after transitioning over to the next surface when rounding a corner.
- Fix a small run-time trajectory bug with the action-handlers for movement around corners.
- Fix support for climbing around with just the grab button.
- Remove SurfaceState.release_(wall|ceiling), which were causing problems with surface updates mid-frame.
- Encode the correct velocity start/end values in ClimbToNeighborSurfaceEdges.
- This fixes a bug with surface-contact transitions not triggering correctly.
- Rename "neighbor" surface to "adjacent" surface.
- Account for max horizontal speed in climb-to-adjacent-surface calculations.
- Fix a surface-state bug with inconsistent touch and grab state.
- Finish ClimbAdjacentSurfacesBehavior.
- Add support in get_intersection_of_segment_and_circle for accessing the second intersection point.
- This is useful for detecting where the maximum distance away from a given point aligns with a given surface.
- Behaviors use this in order to limit the character movement to a given radius.
- Update behaviors to not pause between movement, if the delay is configured as zero.
- Update Behavior._move() to return an enum rather than a bool to represent the result type.
- Update Behavior to support a standard move_target reference, and to check for when it is destroyed.
- Support excluding surfaces that are too far from a basis point that is separate from the target point in SurfaceParser.get_closest_surfaces.
- This is useful for Behaviors, because a Behavior can be configured to keep the character within a given radius from their start position.
- So we then need to be able to navigate the character to a position near some given target, but also not too far from the given start position.
- Add support for anticipates_target_path, anticipates_target_edge, and recomputes_nav_on_target_edge_change in CollideBehavior and RunAwayBehavior.
- Add support for leaving the starting surface in MoveBackAndForthBehavior.
- Distinguish between Behavior start-positions from the latest move call vs the latest activate call.
- Fix a bug with the max-distance threshold in the move-back-and-forth behavior.
- Add support for optionally projecting Behavior overrides into a character's SpawnPosition node.
- Update Behaviors to abort when navigation fails.
- Update various character log events to not be considered low-level, so it's easier to enable them to actually print.
- Refactor character event logging.
- Make it easier to quickly configure log types for debugging.
- Make log formats more standard and easier to scan quickly.
- Fix bug with opacity and the circular-buffer index in the recent-movement annotator.
- Update character annotators to use character-specific colors.
- Update CharacterSurfaceAnnotator surfaces to not be drawn my SurfacesAnnotator.
- Hide character prediction when character-sprite-annotator is disabled.
- Tweak character surface annotator colors.
- Fix ruler annotator opacity and label positions.
- Fix bug with initial-surface attachment for non-floor surfaces.
- Fix a path NPE.
- Fix a bug with bouncify_path leaving gaps when a jump-edge can't be calculated for a given sub-region.
- Fix a rare bug with horizontal motion calculations.
- Fix beat tracking.
- Update Momma Duck for latest framework changes.
- Fix a bug with trying to add jumps to non-floor start/end surfaces.
- Update navigator-calculate-land-position logic to be able to preserve slow-rise gravity (by still "holding the jump button").
- The character-navigator system supports recalculating a new navigation while in the middle of executing a previous navigation.
- However, if the character is in the ascent-part of a jump, with the jump-button-press emulation still active, then the navigator-system currently doesn't preserve this jump-button state—that is, it tries to calculate a new land trajectory that uses only fast-fall gravity, with no remaining slow-rise gravity.
- While holding the jump button and ascending, a smaller gravity value is applied, and the character moves more slowly.
- Then after releasing the jump button or starting descent, a larger gravity value is applied, and the character moves more quickly.
- This makes jumps feel a lot more satisfying for the player.
- This is critical for fixing a handful of navigation failure/interruption issues.
- Add support for fall-through floors and walk-through walls.
- These are the kinds of surfaces that you can either stop on or pass through, depending on what buttons you're pressing.
- A lot of platformers have thin platforms like this.
- You can usually always jump from below.
- More assorted bug fixes and polish work from my current backlog.
