Help with xbox 360 controller

[DerHeadBaanger]

hey guys... i have a problem because when i´m playing Super Mario sunshine the game told me that i have to press the trigger (on my xbox360 controller) only half so that i could spray water when i´m walking (when i´m pressing the trigger completly i´m stop with walking ) now my question : how i can set that, that the game can differentiate if i press the trigger half or full
PS. SORRY FOR MY ENGLISH I`M GERMAN ^^
