textmode.js / input / mouse / MousePosition

Interface: MousePosition

Mouse coordinates in grid space using center-based coordinates.

The coordinate system matches the main drawing/rendering space:

• (0, 0) is the center cell of the grid
• Negative X values are to the left of center
• Positive X values are to the right of center
• Negative Y values are above center
• Positive Y values are below center

When the mouse is outside the grid bounds, both x and y are set to Number.NEGATIVE_INFINITY to indicate an invalid/outside position.

Properties

Property	Type	Description
x	number	Grid X coordinate (column) in center-based coords. Number.NEGATIVE_INFINITY if outside grid.
y	number	Grid Y coordinate (row) in center-based coords. Number.NEGATIVE_INFINITY if outside grid.
