API:ActionButtonGroupSetTintColor

UI Lua API · ActionButtonGroup functions
Version: WAR 1.4.8

Tints one button of an ActionButtonGroup.

ActionButtonGroupSetTintColor(groupName, buttonIndex, r, g, b)

Arguments

groupName: string – Name of an ActionButtonGroup window.
buttonIndex: number – Button number, starting at 1.
r, g, b: number – Red, green and blue on a 0–255 scale. 255, 255, 255 removes the tint.

Nothing.

Bug: the client reads the green value twice and never reads b. The blue channel is always set to the same value as green. Grey tints (r = g = b), which is what the stock UI mostly uses, are not affected.
The values are divided by 255 (fractions are kept). The alpha used is the group's own opacity.
The tint is applied to all the images of that button.
buttonIndex must be between 1 and the number of buttons; otherwise the not a valid ButtonIndex error is raised. Fractions are dropped.
Unlike the other ActionButtonGroup functions, the does not exist message ends with a full stop.
The function also has a No window specified. error, but it never triggers: a missing name is treated as an empty string, which gives the does not exist error instead.

Error in function call 'ActionButtonGroupSetTintColor': Window %s does not exist.
Error in function call 'ActionButtonGroupSetTintColor': Window %s is not a ActionButtonGroup
Error in function call 'ActionButtonGroupSetTintColor': '%d' is not a valid ButtonIndex. (NumButtons = '%d')
Error in function call 'ActionButtonGroupSetTintColor': No window specified. (never triggers)
