[Code] Gun Bobbing or Aminated Weapons - Dugtrio17
If you did the tutorial before May
26, 2003, look for the bold print with the edit.
Gun bobbing: a dream of many. And now you can do it! I
present you an adjustable tutorial on how to implement gun
bobbing in your TC. Quite simple really, and if you want any
change at all, just adjust a few numbers! Once again, it has
been tested from start to finish and works beautifully. If you
have any problems, gimme a yell at Dugtrio17@aol.com. And
Martin and JLB, lemme know if you want it in Kreml or
Battlestein
OK, open Wl_def.h and search for health.
Below int keys, type this:
::: CODE :::
int bobber;
int bobdir; int
bobber2; int
bobdir2;
Bobber is the up
and down bobbing, bobber2 is the left to right bobbing, and
bobdir and bobdir2 are the direction controllers. Save that
and close.
Open up Wl_draw.c and search for
DrawPlayerWeapon. Modify this:
::: CODE :::
if (gamestate.weapon != -1)
{ shapenum =
weaponscale[gamestate.weapon]+gamestate.weaponframe;
SimpleScaleShape(viewwidth/2,shapenum,viewheight+1);
}
if (demorecord || demoplayback)
SimpleScaleShape(viewwidth/2,SPR_DEMO,viewheight+1);
To this:
::: CODE :::
if (gamestate.weapon != -1)
{ shapenum =
weaponscale[gamestate.weapon]+gamestate.weaponframe;
SimpleScaleShape(viewwidth/2-10+gamestate.bobber2,shapenum,viewheight+1+gamestate.bobber);
}
if (demorecord || demoplayback)
SimpleScaleShape(viewwidth/2,SPR_DEMO,viewheight+1);}
You see the adding of the bobber and
bobber2 values. Since these values will change when you walk
(this will be applied next), the gun will bob. Also take a
look at how that 10 is subtracted. Make sure that 10 is equal
to half of whatever you have as the 20 below, or it'll look a
little lopsided. Now save and close that. Open up
Wl_agent.c and search for void Thrust. Below unsigned offset,
add this:
::: CODE :::
if (gamestate.bobdir != 2)
{gamestate.bobber++;} if
(gamestate.bobdir == 2) {gamestate.bobber--;}
if (gamestate.bobber == 10)
{gamestate.bobdir = 2;} if (gamestate.bobber == 0)
{gamestate.bobdir = 1;} if
(gamestate.bobdir2 != 2) {gamestate.bobber2++;}
if (gamestate.bobdir2 == 2)
{gamestate.bobber2--;} if (gamestate.bobber2 == 20)
{gamestate.bobdir2 = 2;} if
(gamestate.bobber2 == 0) {gamestate.bobdir2 =
1;}
EDIT! The tutorial now works on all
systems! See post below. If you did this before May 26, 2003,
take out that DrawPlayerWeapon (); that used to be there.
You'll see where it's put next. Take a close look
at that. When you walk at first, the values will go up, but
once they reach a certain number, the bobdir/bobdir2 values
change, and the gun will bob the other way. Also take a look
at that 20 and that 10. Keep that 20 twice the value of that
10, or your bobbing may look sloped.
Last thing: To
make sure you see the gun bobbing, look for the UpdateFace
function in Wl_agent.c (around 296 in the original code).
ABOVE [if (SD_SoundPlaying() == GETGATLINGSND)], put this:
::: CODE :::
DrawPlayerWeapon();
And there you go! You have a bobbing
gun now. Play around with those numbers up there if you want
(the 20 and the 10); modify them to suit your needs, though I
find those values work great. You could also modify this
tutorial to make certain guns/weapons bob more or less (or not
at all) with a few if statements.
Enjoy, and I hope to
see some people happy about this (especially Zach; when I told
him about the extremely light gun bobbing in Pikachu14's
BorgPanic demo, he got all excited and started typing in all
caps )

Quoting: Zach Attack
You know what we would be an excellent
follow-up to this tutorial? A tutorial on how to make it
possible to have an in-game switch to turn this off or on!
That's not that hard. All you have to
do is add a new variable as the on/off switch for the bobbing
(an int bobberswitch, or something like that. or you could add
a boolean to make a true/false switch, but I'd prefer the
variable).
Open the file wl_def.h, and search for the
'gamestate' type, and add the following line within the
structure:
::: CODE :::
int bobberswitch;
Then modify the start of the thrust
function (from the post above) to look like this:
::: CODE :::
if (gamestate.bobberswitch != 1) // see
below about that != { if (gamestate.bobdir !=
2) {gamestate.bobber++;} if
(gamestate.bobdir == 2) {gamestate.bobber--;}
if (gamestate.bobber == 10)
{gamestate.bobdir = 2;} if (gamestate.bobber == 0)
{gamestate.bobdir = 1;} if
(gamestate.bobdir2 != 2) {gamestate.bobber2++;}
if (gamestate.bobdir2 == 2)
{gamestate.bobber2--;} if (gamestate.bobber2 == 20)
{gamestate.bobdir2 = 2;} if
(gamestate.bobber2 == 0) {gamestate.bobdir2 = 1;}
DrawPlayerWeapon (); }
Of course that != should only be a !=
if you want the gun bobbing to be on automatically from the
start. otherwise, it should be == 1.
Then somewhere
appropriate in Wl_agent.c (though I always keep my "press a
key to do this" functions with the MLI cheat) [EDIT: Never
mind, go ahead and stick it in Wl_play.c], add something like
this:
[EDIT AGAIN:
Revised to set bobbing directions to 0 as well. In fact, I
made it set the variables to zero wrong, too! Cut me some
slack, I did this on the fly ] That 10 should be whatever the 10 is in the
edited ( ) line below. this way, without gun bobbing on, the
gun is drawn as if the gun bobbing never happened.
OK,
I think I got that
right. Someone let me know if I screwed that up, because I
don't have the source with me at this moment.
