Thanks again Joe, your code works.

Now i have a new problem, the lights are rotating also, how do i fix this ?

thanks

32 bit windows XP?  It's kind of admirable you're targeting that, but that encompasses 0.22% of all Steam Users.  You can pretty safely target higher OS versions at this point.

Its what i have, i dont have internet on my computer, to install new windows you need internet.

People can still play my game, persons without steam or internet do also exist.

There is no big market for 2D side scrollers, people who still play that use older game consoles, those are the people i aim for.

As this is for rendering, you could do all your work in shaders, which will be faster still.  Maybe treat each sphere/circle/node of your worms as an instance and utilize instancing to rotate them in the vertex shader.

I would like to, i dont want to learn a shader language, can it be done without ?

With shader you can also make skinned meshes right ?, i would like to make humans walk and move.

First i like to have something simple animated, i will make a new topic about that.

atan2 returns values in the range -pi to pi, corresponding to -180 to +180 degrees. You can add pi to the result to get values in the range of 0 to 2pi.

Who telling you that is not correct, i am sure now.

You could try to make a function that rotates a enemy towards the player with atan2, then you see.

From Wikipedia: This produces results in the range (−π, π]...

I could go on. I mean, you could google this stuff to find out for sure. The internet is literally, like, right there. It's so easy these days, you don't even have to put pants on to do it.

I am not limiting the input in any way, maybe that is why then ?

Here is proof that learning from a book you become a parrot.

You should use it like i asked you to have my proof.

Lets stop this disscussion please, or let someone join the discussion.

Here is the code i use :

aimrot = -atan2f( x - player.x , y - player.y );

if( aimrot > D3DX_PI )aimrot -= D3DX_PI * 2.0f;

Its around the center of the universe, try it.

Please lets focus on why the lighting is not correct in the mesh, maybe it has to do with normals in the matrix ?

I dont know the exact values, or might the D3DX_PI value incorrect ?

I am not trying to find these values, no time.

I wish it was true to avoid the if.
