[SDL code]More "doomish" gun bobbing.

I got this idea from Tricobs thread for creating more Doom-like movement...
First use this gun bobbing-routine by BrotherTank as a base (if you haven't
installed gun bobbing yet)...

Now in wl_agent.c go to Thrust() and change the values to these:

Code:


  if (gamestate.bobdir != 1) gamestate.bobber++; else gamestate.bobber--;

  if (gamestate.bobber == 20 || gamestate.bobber == 0) gamestate.bobdir ^= 1;

  if (gamestate.bobdir2 != 1) gamestate.bobber2++; else gamestate.bobber2--;

  if (gamestate.bobber2 == 40 || gamestate.bobber2 == 0) gamestate.bobdir2 ^= 1;



Now open up wl_draw.c and search for SimpleScaleShape... Change it to this form:

Code:


void SimpleScaleShape (int xcenter, int shapenum, unsigned height,int spc);


Now add '0' as spcs value in every single reference to SimpleScaleShape except
in the one found in DrawPlayerWeapon(). After you have done this - go to the
DrawPlayerWeapon() look for a line looking like this:

Code:

 SimpleScaleShape((viewwidth/2)-10+gamestate.bobber2,shapenum,viewheight+1+gamestate.bobber);

And replace it with this:

Code:


        SimpleScaleShape((viewwidth/2)-10+gamestate.bobber2,shapenum,viewheight+1,1);

    //  SimpleScaleShape((viewwidth/2)-10+gamestate.bobber2,shapenum,viewheight+1+(gamestate.bobber*2),0);



Now you might wonder what does the line commented out do - it is only for comparasion...
Then we have to go to the SimpleScaleShape() and edit it a bit to make this code work...

Search for this line in SimpleScaleShape():

Code:

upperedge=viewheight/2-scale;


And replace it with this:

Code:

    if(spc==1)

      upperedge=viewheight/2-scale+(gamestate.bobber*2);

    else

      upperedge=viewheight/2-scale;


Now when you recompile your source - instead of weapon scaling
smaller / larger while moving - it actually "bobs" up and down.

NOTE: This code should work with the original DOS-side of code aswell...

Nice code WLHack! I am looking to getting into the SDL for my Episode 3 mod, but that won't be for a while still. I love that you are doing SDL code tutorials on this forum. But what we really need is a tutorial explaining SDL, what program is needed to compile (like code blocks) and exactly how to start working with SDL and compiling it. I have absolutely no idea how to start up any of that. I would also like to "convert" my first two episodes to SDL, just not sure what is all involved.

Okay... I will write a general tutorial for SDL during the weekend.

You da' man Hack'
