env_texturetoggle是一个点实体(en)，可在所有的 起源 游戏中使用。 It allows you to change the textures on brush entities or overlays.

Entity Description

LightmappedGeneric
{
  $basetexture "path/to/a/VTF/file/with/multiple/frames"
  Proxies
  {
    ToggleTexture
    {
      ToggleTextureVar         $basetexture
      ToggleTextureFrameNumVar $frame
    }
  }
}

In order for env_texturetoggle to work properly, your overlay or at least one face of your brush must use a VMT material with the ToggleTexture proxy defined and pointing to an animated VTF file with at least two frames.

Such a VMT file could look like the one on the right.

示例: If we have a brush entity named brush and an env_texturetoggle named toggle whose target brush is brush, then we can use any of the following outputs on a func_button to toggle the texture for the brush. The second and third output have the same effect.

Inputs to toggle textures

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnPressed	toggle	IncrementTextureIndex		0	No
	OnPressed	toggle	SetTextureIndex	<n>	0	No

注意:If a brush has multiple textures with multiple frames, an output will affect all of these textures.

代码:An entity's texture frame can be set via code using the SetTextureFrameIndex() function.

错误:Identical textures on visible unnamed overlays may also be impacted.  (tested in： )

Keyvalues

Name (目标名称) <target_source>[ Edit ]

这个名称是其他实体通过 输入/输出(en) 或其他 关键值(en)（如 parentname 或 target) 来引用该实体时使用的标识符。
该名称也会显示在 Hammer 编辑器的 2D 视图和 实体报告(en) 中。

参见:  所有实体均可使用的 通用键值、输入与输出(en)

Target Brush(es) (target) <target_destination>

Name of the brush entities or overlays. All ToggleTexture materials on all entities (including sprites) matching the targetname will be affected.

Inputs

IncrementTextureIndex <void>

Increments target brush's current texture frame by one. In other words: switches to the next texture.

SetTextureIndex <整数(en)>

Sets target brush's texture frame to the specified index.

注意:While this parameter takes an integer, it writes to an unsigned char without any bounds checking. Values above 255 or below 0 will  overflow.
