---|
[1349] | 52 | |
---|
[6084] | 53 | Every input device has its own wrapper class which does the actually input event |
---|
[3327] | 54 | distribution. The InputManager only creates reloads (on request) those devices. |
---|
[973] | 55 | |
---|
[3327] | 56 | The other functionality concerns handling InputStates. They act as a layer |
---|
| 57 | between InputHandlers (like the KeyBinder or the GUIManager) and InputDevices. |
---|
| 58 | InputStates are memory managed by the IputManager. You cannot create or destroy |
---|
| 59 | them on your own. Therefore all states get destroyed with the InputManager d'tor. |
---|
| 60 | @note |
---|
| 61 | - The actual lists containing all the InputStates for a specific device are stored |
---|
| 62 | in the InputDevices themselves. |
---|
| 63 | - The devices_ vector always has at least two elements: Keyboard (first) and mouse. |
---|
[6084] | 64 | You best access them internally with InputDeviceEnumerator::Keyboard/Mouse |
---|
[3327] | 65 | The first joy stick is accessed with InputDeviceEnumerator::FirstJoyStick. |
---|
| 66 | - Keyboard construction is mandatory , mouse and joy sticks are not. |
---|
| 67 | If the OIS::InputManager or the Keyboard fail, an exception is thrown. |
