What is happening right now?

<< Codes Omitted >> Which is better???

I think you are not able to understand Sorry for my poor grammars I apologise Let us take an example If i hold the enter key down the obj moves And when i release the enter key the obj stops moving. Like that only when i hold the mouse button down obj will start moving and when i release the mouse button (up) it should stop moving automatically like the enter key If i am not wrong i think your code will only stop the obj when the mouse pressed null I want obj to stop moving automatically when the mouse button is released
