| // THREEx.KeyboardState.js keep the current state of the keyboard. | ||
| // It is possible to query it at any time. No need of an event. | ||
| // This is particularly convenient in loop driven case, like in | ||
| // 3D demos or games. | ||
| // | ||
| // # Usage | ||
| // | ||
| // **Step 1**: Create the object | ||
| // | ||
| // ```var keyboard = new THREEx.KeyboardState();``` | ||
| // | ||
| // **Step 2**: Query the keyboard state | ||
| // | ||
| // This will return true if shift and A are pressed, false otherwise | ||
| // | ||
| // ```keyboard.pressed("shift+A")``` | ||
| // | ||
| // **Step 3**: Stop listening to the keyboard | ||
| // | ||
| // ```keyboard.destroy()``` | ||
| // | ||
| // NOTE: this library may be nice as standaline. independant from three.js | ||
| // - rename it keyboardForGame | ||
| // | ||
| // # Code | ||
| // | ||
