The movie below lets you use keys to move the blob.
Look at the code and try to determine what keys can move and rotate the blob.
It is much easier to understand the code now becasue we have used the Keyboard constants instead of the code numbers:
stage.addEventListener(KeyboardEvent.KEY_DOWN, doKeyDown);
function doKeyDown(e:KeyboardEvent):void {
var amount:int=1; //amount to move by
if(e.shiftKey) amount=5; //make it 5 if shift is down
switch(e.keyCode) {
case Keyboard.DOWN: blob.y+=amount; break; //down arrow case Keyboard.UP: blob.y-=amount; break; //up arrow case Keyboard.LEFT: blob.x-=amount; break; //left arrow case Keyboard.RIGHT: blob.x+=amount; break; //right arrow
case Keyboard.R: //letter r
if(e.shiftKey) amount=-1; //if shift is down rotate counter clockwise
else amount=1;
blob.rotation+=amount; //rotate when r is pressed
break;
} //switch
} //doKeyDown
Notice that we do not need curly braces {} around the statements for the letter r: the break ends the block with case rather than curly braces. Download the FLA file
