Brush Entity

This entity lets you switch a train that is <I>not</I> being controlled by the player to a new track via a moving piece of track, either rotating, or ascending / decending, or both.

Attributes

• Name (targetname) - Property used to identify entities.
• Render FX (renderfx) - Gives objects special render effects. Think of it as modifying whatever the Render Mode puts out. The options are as follows:

[list]
[li]0 = Normal

• 1 = Slow Pulse
• 2 = Fast Pulse
• 3 = Slow Wide Pulse
• 4 = Fast Wide Pulse
• 5 = Slow Fade Away
• 6 = Fast Fade Away
• 7 = Slow Become Solid
• 8 = Fast Become Solid
• 9 = Slow Strobe
• 10 = Fast Strobe
• 11 = Faster Strobe
• 12 = Slow Flicker
• 13 = Fast Flicker
• 14 = Constant Glow
• 15 = Distort
• 16 = Hologram (Distort and Fade)[/li]

[li]Render Mode (rendermode) - Controls the type of rendering that is used for an object. Options are:

• 0 = Normal
• 1 = Color
• 2 = Texture

• 4 = Solid
• 5 = Additive[/li]

[li]Move Sound (movesnd) - These apply either to door or elevator type entities. For doors, the options are as follows:

• 0 = No Sound

• 6 = Large Rollers
• 7 = Track Door
• 8 = Snappy Metal Door

And for elevators:

• 0 = No Sound
• 1 = big elev 1
• 2 = big elev 2
• 3 = tech elev 1
• 4 = tech elev 2
• 5 = tech elev 3
• 6 = freight elev 1
• 7 = freight elev 2
• 8 = heavy elev
• 9 = rack elev
• 10 = rail elev
• 11 = squeek elev
• 12 = odd elev 1
• 13 = odd elev 2[/li]

[li]Stop Sound (stopsnd) - This property is found in both door and elevator type entities. For doors, the options are:

• 0 = No Sound
• 1 = Clang with brake
• 2 = Clang reverb
• 3 = Ratchet Stop

• 2 = big elev stop 2
• 3 = freight elev stop
• 4 = heavy elev stop
• 5 = rack stop
• 6 = rail stop
• 7 = squeek stop
• 8 = quick stop[/li]

[li]FX Amount (renderamt)[/li]
[li]FX Color (rendercolor)[/li]
[li]Global Entity Name (globalname)[/li]
[li]Sound Volume (volume) - Range: 0.0 - 1.0[/li]
[li]Travel altitude (height) - Altitude to ascend or descend (use negative values for the latter, or 0 to disable altitude change).[/li]
[li]Spin Amount (rotation) - This is the amount in degrees the track will turn on its way up / down.[/li]
[li]Train to Switch (train) - The Name of the train that is using the track.[/li]
[li]Top Track (toptrack) - This is the Name of the last path_corner in the upper track.[/li]
[li]Bottom Track (bottomtrack) -The Name of the first path_corner in the lower track.[/li]
[li]Move/Rotate Speed (speed) - The speed in units/sec that the track platform will move. If the Rotate Only flag is set this will be the speed of rotation only.[/li]
[li]ZHLT Lightflags (zhlt_lightflags)[/li]
[li]Light Origin Target (light_origin)[/li]
[li]Minimum Light Level (_minlight)[/li]
[/list]

Flags

• Auto activate train (1) - ??
• Relink track (2) - ??
• Start at bottom (8) - Moving track will start in the bottom position.
• Rotate only (16) - Track will not move up and down.
• X axis (64) - Rotate around the X axis.
• Y axis (128) - Rotate around the Y axis.

Inputs

Outputs

Notes

• It is important that the last path_track should <I>not</I> have a Next Stop Target. For this path_track to function correctly, set the property Fire on Dead End to the Name of the func_trackautochange.

• An origin brush needs to be part of the entity to specify its axis of rotation.

• The axis defaults to Z if neither of the axis flags is enabled.
