The sixth parameter is “Mode”.
Here you can add various conditions and settings to the polygon. The macros that can be specified here are as follows.

Table 7-4 Mode

You can specify one option for each group.
Use the or operator “|” for continuous notation.
Omitted groups are treated as if defaults were specified.

Caution
Not all groups can be abbreviated. If you want all to be the default, specify “No_Window” as a dummy.

The group [5] is for specifying the texture color mode, so be sure to set the default ("CL_16Bnk" or not specified) when not using the texture. If another mode is specified here, polygons will not be displayed.

As an exception for group [6], “CL_Gouraud |-CL_Half” and “CL_Gouraud |-CL_Trans” can be used. Use this when you want to use semi-luminous Gouraud shading, translucent Gouraud shading .
When using Gouraud shading, it is necessary to set “CL_Gouraud” here together with the setting of the fifth parameter.
When using semi-brightness, translucency, and Gouraud shading, only RGB direct and texture 32768 color RGB modes are supported for polygons. Note that other settings cannot be displayed correctly.
