Tile Wall Identifier Properties - frasergeorgeking/UE4_BP_MazeGen_MIT GitHub Wiki

This section has been divided into two catagories - Variables and Events. Each category itemises the key properties of a given variable/event and provides screenshots where applicable.

The individual names of each variable/event are based on how they are defined within the BP_MazeController class - different names or summaries may be used elsewhere in the project, such as within the Editor Utility Widget interface.

Variables

Please find itemised documentation on the public variables of the tile wall identifier below - these variables determine both which tile actors are targeted, as well as the functionality of the line trace based wall identification process.

Target Tile Actors

images/wall-ident-props/target_tile_actors.png

An array of actor references to tiles in the scene. Must be manually populated via the Actor Picker.

Z Axis Line Trace Offset

images/wall-ident-props/z_axis_offset.png

The Z axis offset from the origin of the tile geometry, used as the start location for the line trace. Useful for tiles with gaps in the geometry which may result in the default location of the line trace missing.

Line Trace Range

images/wall-ident-props/line_trace_range.png

Determines the length of the line trace - a higher LineTraceRange = a longer line trace. Length can be previewed via calling Preview Line Trace Range with Debug Lines.

Exported CSV File Name

images/wall-ident-props/exported_csv_name.png

The file name of the generated CSV. If left blank, file name will be auto generated based on current date and time.

Events

Please find intemised documentation on the public events of the maze controller below - these events are used to debug wall identifier settings and automatically generate tile data tables.

Preview Line Trace Range With Debug Lines

images/wall-ident-props/prev_line_trace.png

Uses the Debug Line functionality of UE4 to preview the line trace range, as determined by LineTraceRange.

Test Line Trace

images/wall-ident-props/test_line_trace.png

Performs a Line Trace By Channel using the currently set properties. Allows a user to preview if the correct walls are hit.

Flush Debug Lines

images/wall-ident-props/flush_debug_lines.png

Removes all debug lines drawn by PreviewLineTraceRangeWithDebugLines and/or TestLineTrace.

Export Values to CSV

images/wall-ident-props/export_values_to_csv.png

Creates a tile data table for each TargetTileActor in each individual orientation (0°, 90°, 180° & 270°).
