2 Issues
Buttons are able to be pushed from behind walls (within a certain thickness) completely outside line-of-sight. If you want to prevent this, consider making adjustments to the button's position, or using a setup that locks the button via multisource that unlocks when a player reaches a trigger that is directly in front of the button so that it is usable from there.
3 Flags
1 : Don't move
If set, this func_button won't move when pressed and be activated instantly instead.
32 : Toggle
If set, this func_button will ignore its delay before reset and be toggleable instead, switching between the texture states whenever pressed, if such a texture is assigned on one of its faces. The delay before reset still needs to be greater than zero in order for this to work, though.
64 : Sparks
If set, the func_breakable ocassionally emits sparks. You can use this for easily creating buttons which appear to be broken.
256 : Touch activates
If set, this func_button can be activated by touching it. This disables activating per use-key.
4 Changes
5.0 Steam Release: Added 'Inventory Rules', 'Sound Override', 'Locked Sound Override', 'Unlocked Sound Override', 'Locked Sentence Override' and 'Unlocked Sentence Override' keyvalues. 5.11: Added 'Use Type' keyvalue.
