I just wrote a little tutorial on request about some basic demo effects. thought I might as well post it here

Pretty good tutorial. I'm especially thankful of the sine stuff as I'm pretty bad with trigonomitry and stuff. I'll be sure to check it out more in-depth later.

I just have a small suggestion.
This -> if (x>=0&&x<ScreenWidth&&y>=0&&y<ScreenHeight) looks way to cluttered...

It should look like
this -> ((x >= 0) && (x < ScreenWidth) && (y >= 0) && (y < ScreenHeight))

Not only is it much easier for you to read, but also for the compiler, in some cases.

thx for the suggestion, i just fixed that in the tut

No problem.

Remember that it's better to overuse parenthesis than using next to none. Also, try to add spaces between values, operators etc. What I mean is, don't write x*y=z but x * y = z. It's not necessary as the compiler understand both it either way but it certainly is easier to read.

i'm just too lazy
yeah but readability is important when you work in teams and sharing source codes...
actually i was trying to read some asm code i wrote 2 years ago and i was like how the fuck did i do that lol

Heh yeah it happends. That's why I try to comment and organize my code as good as possible.
