How to detect if a button is in range

How do I know if a player can press a button (he is close enough) to use it?

Loop all "func_button" entities in a X radius around the player using the "find_sphere_class" function.
You can find the X by doing a simple test - adding a chat message when you press a button that prints out the distance between the player and the button entity.

Or I guess you can look in the game's code to find the 100% accurate distance.

//Edit: I believe the radius is 64 according to this:

Code:

// 
// PlayerUse - handles USE keypress
//
#define PLAYER_SEARCH_RADIUS (float)64
