Draft Specification: Tiles Of Interest

• Feedback needed!

• The main motivation behind this is to show the tile locations of various buildings' interaction points, especially where they are not obvious or are in a different location than expected from the game's animations.

Tile coordinates

This draft uses the following rules for specifying TOI tile locations, which I propose should be the standard if found to be acceptable:

• Use numbers, not text. This is for clarity and consistency, and for template/module coding ease.
• Point-of-origin (x1, y1) is the bottom-left tile. This is where the TOI is for most buildings, and is more or less consistent with left-to-right reading/numbering for most English-speaking locales.
• Specifying the y axis (row) is optional if the TOI is on the first (bottom) row. This will be the location for most buildings.
• If a building has multiple TOI and they are all at the same location, a single "catch-all" TOI may be specified. (not 100% sure about this, might complicate coding?)

Example #1, grid (with explicit numbering):

1,4	2,4	3,4	4,4
1,3	2,3	3,3	4,3
1,2	2,2	3,2	4,2
1,1	2,1	3,1	4,1

Based on the above rules, most buildings will have their TOI at tile coodinate 1.

Example #2, from an image:

In this case the Dupe TOI is 2. This image is also a good example of a misleading animation.

Statistical summary

From this reddit post :

There are:

• 8 one-tile-wide buildings with a TOI at position 1 that serves one or more functions
• 16 two-tile-wide buildings with a TOI at position 1 that serves one or more functions
• 5 three-tile-wide buildings with a TOI at position 2 that serves one or more functions
• 9 four-tile-wide buildings with a TOI at position 2 that serves one or more functions

• 3 buildings have multiple Dupe TOI.

• 13 buildings do not fit into any of the categories above

• 34 buildings have no data as yet

• Most, but not all, TOI are rotated/flipped with their building as expected.

TOI types / functions

Preliminary type names & type ID numbers.

ID	Name	Description	Remarks
1	Dupe	Duplicant operation / interaction	The tile that dupes need to access to make the building work. Also important for positioning pressure plates and lighting. The in-game animations are inaccurate for at least four buildings.
2	Input	Delivery point	The tile that must be accessible by dupes/auto-loaders to supply the building with any needed resources.
3	Output	Material output	Where the building drops any generated resources and/or by-products.

Annotations

(Not yet finalized)

• Squares coloured by TOI type?
• Just text maybe? Could use first character of each type name (D/I/O). An asterisk could mean "all types".
• Probably helpful to superimpose a grid.

(mock-up some examples here)

Template/module considerations

• Multiple superimposition layers.
• Image, layer, and annotation scaling.
• Handle tile-based coordinates.
• Existing building images (from the GUI) are not scaled consistently.
• Multiple, potentially overlapping, TOI annotations.
• Some buildings can be flipped/rotated.
• Some buildings are slightly bigger than their tile size would indicate.

Specific building Remarks

• If the Polymer Press is flipped, its TOI does not mirror its position as expected, and is also outside the building's 3-tile footprint (TOI 1 becomes 4!). (needs verification in-game)
• The Printing Pod's output TOI is between its middle two tiles (2 and 3). Probably best to handle it as a one-off? Should note that pressure plates won't trigger. (needs verification in-game)

Test cases
