OH!!

That makes sense. Thanks for the help!

[VeryAngryBeaver]

@rockindahizzy its the equivelant of

bitmap.regX = Math.floor(bitmap.image.width/­2);

the reason to use |0 instead is because it runs faster

[rockindahizzy]

Could you explain the use/reasoning behind the "|" in the following lines (I couldn't find anything on Google. Mainly cause I did not know what to look for):

bitmap.regX = bitmap.image.width/2|0;

bitmap.regY = bitmap.image.height/2|0;

ship.y = canvas.height*Math.random()|0

Thanks!!! I am enjoying going through your video tutorials. Very Helpful!
