getKeyStates
public int getKeyStates()
Gets the states of the physical game keys. Each bit in the returned integer represents a specific key on the device. A key's bit will be 1 if the key is currently down or has been pressed at least once since the last time this method was called. The bit will be 0 if the key is currently up and has not been pressed at all since the last time this method was called. This latching behavior ensures that a rapid key press and release will always be caught by the game loop, regardless of how slowly the loop runs.
For example:
// Get the key state and store it
int keyState = getKeyStates();
if ((keyState & LEFT_KEY) != 0) {
positionX--;
}
else if ((keyState & RIGHT_KEY) != 0) {
positionX++;
}
Calling this method has the side effect of clearing any latched state. Another call to getKeyStates immediately after a prior call will therefore report the system's best idea of the current state of the keys, the latched bits having been cleared by the first call.
Some devices may not be able to query the keypad hardware directly and therefore, this method may be implemented by monitoring key press and release events instead. Thus the state reported by getKeyStates might lag the actual state of the physical keys since the timeliness of the key information is be subject to the capabilities of each device. Also, some devices may be incapable of detecting simultaneous presses of multiple keys.
This method returns 0 unless the GameCanvas is currently visible as reported by Displayable.isShown(). Upon becoming visible, a GameCanvas will initially indicate that all keys are unpressed (0); if a key is held down while the GameCanvas is being shown, the key must be first released and then pressed in order for the key press to be reported by the GameCanvas.
Returns:
An integer containing the key state information (one bit per key), or 0 if the GameCanvas is not currently shown.
