Func button (GoldSrc)

func_button is an e2 available in all GoldSrc games.

Warning:

• The {{{engine}}} parameter is inconsistent with the name defined by the {{gldsrc}} template. This can most likely be fixed by setting the value of the {{{engine}}} parameter to GoldSrc.
  If a parameter is consistent but you're still seeing this warning, it may be an issue with the template itself. Please discuss it on the template's talk page.

The button can be used to trigger an event when it is touched or used. When the button is touched or used, it will move in the direction set by its angle, for a length equal to its own length. Following is a list of its important properties.
