This tutorial is Great!. there is typo error, the left (0,-1) in image and explanation should be (-1,0)

A lot of this tutorial is unnecessarily complicated. Just notice that the plane is divided into 4 parts by lines x + y = 0 and x - y = 0. So just compute x + y and x - y, and depending on weather those values are negative or nonegative you will know which animation to use.

This is by far the most elaborated tutorial i've ever seen. Nice job with the math function... the way you explained it. ITS AWESOME !!!

@maradona640 there is less math involved so it might be easier to understand for some

[maradona640]

i found it easier to understand if you use variables for the currentRow and column and then depending on the wall that was hit, to change the current column accordingly

I used absolute value instead of arctan. Im only showing code for the left/right check. But I also have code for the up/down check but youtube wont let me put it.

if(Math.abs(xSpeed)>Math.abs(y­Speed)){//moving sideways

if(xSpeed>0)//moving positive--RIGHT

currentDirection=2;//RIGHT-fro­m sprite sheet

else

currentDirection=1;//LEFT-from sprite sheet

then in onDraw...int srcY = currentDirection * height;
