# Side
|
||
|
|
||
|
Also known as a "sidedef." One of the textured sides of a line. Each sidedef
|
||
|
has three portions: Upper, middle, and lower. The middle texture is special as
|
||
|
it can have translucency.
|
||
|
|
||
|
The three portions of a sidedef can be referred to with:
|
||
|
|
||
|
| Name | Description |
|
||
|
| ---- | ----------- |
|
||
|
| `Side.Top` | The upper portion. |
|
||
|
| `Side.Mid` | The middle portion. |
|
||
|
| `Side.Bottom` | The lower portion. |
|
||

|
The line this side belongs to.
|
||
|

Any combination of the following bit flags:
|
||
|
|
||
|
| Name | Description |
|
||
|
| ---- | ----------- |
|
||
|
| `WALLF_ABSLIGHTING` | Light is absolute instead of relative to the sector. |
|
||
|
| `WALLF_CLIP_MIDTEX` | Clips the middle texture when it goes under the floor or above the ceiling. |
|
||
|
| `WALLF_LIGHT_FOG` | The wall's lighting will ignore fog effects. |
|
||
|
| `WALLF_NOAUTODECALS` | Don't attach decals to this surface. |
|
||
|
| `WALLF_NOFAKECONTRAST` | Disables the "fake contrast" effect for this side. |
|
||
|
| `WALLF_POLYOBJ` | This sidedef belongs to a polyobject. |
|
||
|
| `WALLF_SMOOTHLIGHTING` | Applies a unique contrast at all angles. |
|
||
|
| `WALLF_WRAP_MIDTEX` | Repeats the middle texture infinitely on the vertical axis. |
|
||
|
|
||
|
- `Light`
