Roads, pathfinding & points of interest

Sapphire

  • Improve HUD text visibility
    • DONE Added semitransparent background to HUD, and changed text colour to white.
    • DONE Changed to using system UI font.
  • HF tools:
    • TODO Make tool window appear, for first time, in top-right corner of Sapphire.
    • TODO Add spin controls for radius & such
    • TODO Add 'PerlinRaise' and 'PerlinLower' tools (see request.)
    • DONE Updated display of bulldozer / etc. tools.
    • DONE Smooth edge of Perlin tool (see request).
  • Fix support for large heightfields
    • TODO Move ROAM patches to CsHeightfieldTile class (requires patch size to be divisor of tile size?)
    • TODO Implement dynamic loading / freeing of tiles (with re-tessellation, etc.)
    • TODO Optimise triangle pool usage between tiles
  • TODO Document path recording / playback.
  • Improve rendering of camera paths and teleport points.
    • TODO Use better camera mesh (saved as zmesh?)
    • TODO Add text overlay above camera teleport point.
  • TODO Add support for loading arbitrary point lists (from CSV) as paths.
  • TODO Use GLSL shaders to provide better terrain detail, and for fog.
  • TODO Use GLSL shaders for waves, water reflection, refraction (inc. underwater view)
  • TODO Use VBOs for terrain patches.

User-defined grids

  • TODO Add option for user-defined grid overlay, where user sets extents, and tile sizes. Note grid does not need to cover entire map.
  • TODO Allow import & export of grid definitions.
  • TODO Show grids in Sapphire.
  • TODO Add option for 'snap to grid' with mouse selection tool (see request).
  • TODO Add 'select tiles' window (possibly using existing 'select area' window.)
  • TODO Add ability to set grid tile names, and display names in 2D and 3D view (see request, also here).

ZeoGraph

  • DONE Add pin passthrough rendering, to make it clear when a filter's output is the same as its input (i.e. map handles being passed through verbatim).
    • DONE Ensure passthroughs are loaded/saved in CzFilter::Serialise and CzFilter::Deserialise (example is zg_tee, where all passthroughs are created dynamically)
    • DONE Apply to script filters too.
    • TODO Verify all filters (both script & plugins) set all passthroughs correctly (see 'tests/FiltersToFix.zgraph').
    • TODO Update docs.
  • DONE Added flags to CzFilterFactory::RegisterFilter function, including:
    • ZFF_CLASS_DEPRECATED, which hides filters from 'add new filter' dialog box (but allows existing filters in graphs to be supported).
  • DONE Modified GetProjectMap2 to allow 'options' edit of map name input pin too. If name input is disconnected, options button allows edit of map name. If pin is connected, options button says “Map name option is controlled by '[filter name]' filter connected to 'MapName' pin”.
    • DONE Repeated for SetProjectMap2 too.
    • DONE Deprecated GetProjectMap and SetProjectMap, which are now redundant (using new ZFF_CLASS_DEPRECATED flag).
  • DONE Modified GetProjectMap2 to allow choice of creating local copy or not (previous default was yes).
  • DONE Modified project.SetProjectMap2 to automatically save undo points.
    • TODO Update ZG_project plugin & filter documentation.
    • DONE Removed manual backup scripts from example graphs.
  • DONE Reorder insane calc.HF.Exponential pins, before it's too late :!: (also drop hOutputMap input pin).
  • TODO Add lowpass filter (sinc convolution), and highpass filter (subtraction of lowpass filter); see https://en.wikipedia.org/wiki/Low-pass_filter#Ideal_and_real_filters.
  • TODO Added 'Load graph…' menu item to L3DT, for opening ZeoGraph and loading file.
  • DONE Added UI.EditValue filter in new 'ZG_UI' plugin.
    • TODO Document!
  • DONE Added UI.EditValueEx filter, for multiple values.
    • TODO Document!
  • DONE Add General.Wait and General.WaitTrigger filters.
    • TODO Document!
    • DONE Also added support for void pin types, for dataless flow control.
  • DONE Added calc.HF.SquareRoot filter.
    • TODO Document!
  • TODO Add passthrough hMap pin to project.SetProjectMap filter.
  • TODO Add UI.ComboSelector filter, for selecting from a set of values (output is int for index, AND string for value)
  • TODO Add UI.MessageBox filter (simple notification, icon style is option, as combobox; prompt input only)
    • TODO Document!
  • TODO Add UI.YesNoQuestion filter, which returns true or false.
    • TODO Document!
  • TODO Add UI.YesNoQuestionSwitch filter, which passes an input variable between yes or no outputs (uses disable behaviour).
    • TODO Document!
  • TODO Allow external scripts &c to set input variables (i.e. the variable.xyz filters, also pins of named filters)

Bug fixes

  • DONE Ensure edit record is closed in Sapphire when mouse mode changes (and other similar cases), to eliminate 'cannot create edit record' errors (see bug report).

  • DONE Fixed bug in ZeoWrap, where combosel.GetCurSelA was incorrectly named combosel.GetPathCurSelA.

  • TODO DM editing doesn't always mark HF as dirty (see this thread.)
  • DONE Extended timeout to prevent errors on startup.
