A Figure Drawing addon enables you to add a set of grid points where by choosing two points you can draw or remove the segment connecting the two points. This addon can be used to draw figures.
In the drawing mode, it is possible to use either the click&click operations to select the two points that make a segment or drag the line from one point to another with the drag&drop method.
In the coloring mode, the already drawn figures can be colored using the available color palette.
The list starts with the common properties, learn more about them by visiting the Modules description section. The other available properties are described below.
|3D grid||Enables to change the grid into a pseudo 3D grid.|
|Show grid||Enables to hide or show the grid lines.|
|Point radius||This property defines the radius of the point. If left empty, it is equal to 5.|
|Starting lines||This property allows to define the segments that will be visible at the beginning.
Define the segment by writing the column and the row of its points separated with a dash (the column and the row are separated with a semicolon). A definition of different segments should be written in separate lines.
If you want the line to be removable, add an asterisk (*) after the second point.
|Answer lines||This property allows to define the segments that are to be drawn as the answer.
Define the segment by writing the column and the row of the points separated with a dash (the column and the row are separated with a semicolon). A definition of different segments should be written in separate lines.
|Is activity||Enables to define whether the module is an activity or not.|
|Is disabled||Allows disabling the module so that the user is not able to interact with it.|
|Coloring||This property allows users to color the figures drawn in the addon.|
|Default Color||This property allows to define the default color for coloring figures. The color needs to be define in the RGB format, e.g.:
255 10 255
|Starting Colors||This property allows users to define the colors in which the figures are colored at the beginning.
It's a new line separated property. The single line should contain x, y of the point inside the figure and the color in RGB format, e.g.:
105;35;0 255 255
47;127;255 100 0
|Answer Colors||This property allows users to define the figures which need to be colored.
In the "Figure" property, define the figure you want to color by writing the points of the figure (the figure needs to be closed, so the first and the last points have to be the same), e.g.:
In the "Point and Color" property, define a point inside this figure and the color in RGB format, e.g.:
50;50;255 10 10
|Block coloring mode until all lines are OK||If this property is selected, the coloring mode is blocked until all lines are correct. Then, when all lines are correct, the addon automatically changes to the coloring mode.|
|Show Answers in Editor||If this property is selected, the defined answers are shown in the Editor.|
The Figure Drawing addon sends ValueChanged type of events to Event Bus when a line is drawn or removed.

When all lines are drawn correctly, the addon sends another event.
In the coloring mode, the addon sends ValueChanged type of events to Event Bus when a figure is colored.

|score||1 point for each correct line and 1 point for each correctly collored figure.|
|errorCount||1 error point for each incorrect line and 1 error point for each figure that has the correct boundaries but its color is wrong.|
