- Increase font size and decrease pixel size.
- The font is rendered at the same physical size, but is more detailed,
which is visible when the camera is up close.
- Add an outline to improve readability on mixed-color backgrounds.
- The outline is fairly thick to ensure it doesn't get too grainy
at a distance (without requiring MSDF or mipmaps on the default
project font).

|
<constant name="FLAG_DOUBLE_SIDED" value="1" enum="DrawFlags">

|

</constant>
|
|
<constant name="FLAG_DISABLE_DEPTH_TEST" value="2" enum="DrawFlags">
|
|
Disables the depth test, so this object is drawn on top of all others. However, objects drawn after it in the draw order may cover it.
|

|
|
Label is scaled by depth so that it always appears the same size on screen.
|
|
</constant>
|
|
<constant name="FLAG_MAX" value="4" enum="DrawFlags">
|
|
Represents the size of the [enum DrawFlags] enum.
|
|
</constant>
|
|
<constant name="ALPHA_CUT_DISABLED" value="0" enum="AlphaCutMode">
|
|
This mode performs standard alpha blending. It can display translucent areas, but transparency sorting issues may be visible when multiple transparent materials are overlapping.
|
|
</constant>
|
|
<constant name="ALPHA_CUT_DISCARD" value="1" enum="AlphaCutMode">
|
|
This mode only allows fully transparent or fully opaque pixels. Harsh edges will be visible unless some form of screen-space antialiasing is enabled (see [member ProjectSettings.rendering/anti_aliasing/quality/screen_space_aa]). This mode is also known as [i]alpha testing[/i] or [i]1-bit transparency[/i].
|
|
[b]Note:[/b] This mode might have issues with anti-aliased fonts and outlines, try adjusting [member alpha_scissor_threshold] or using MSDF font.
|
|
[b]Note:[/b] When using text with overlapping glyphs (e.g., cursive scripts), this mode might have transparency sorting issues between the main text and the outline.
|
|
</constant>
|
|
<constant name="ALPHA_CUT_OPAQUE_PREPASS" value="2" enum="AlphaCutMode">
|
|
This mode draws fully opaque pixels in the depth prepass. This is slower than [constant ALPHA_CUT_DISABLED] or [constant ALPHA_CUT_DISCARD], but it allows displaying translucent areas and smooth edges while using proper sorting.
|
|
[b]Note:[/b] When using text with overlapping glyphs (e.g., cursive scripts), this mode might have transparency sorting issues between the main text and the outline.
