Stuck on a Force Power

JediBantha · May 13, 2013

I was playing around with existing powers, and decided to throw in a new one.
however, being a newcomer in terms of coding, I couldn't figure out how to make it actually "work" - Putting it in my Force arsenal, and the datapad menu was the farthest I got.

It'd help if we knew what exactly you were trying to add/do.

JediBantha · May 13, 2013

What I'm trying to do is replicate the KotOR power "Stun" into JKA (to the right of "Mind Trick" in the link provided), by editing the ForceGrip code in the "wp_saber.cpp" file.

Like I said, I managed to put it in my Force arsenal, as well as the Datapad Menu, but that's as far as it went - Didn't even hold them in place.

Provide your code please, or its really hard to help you out.

what position is FP_STUN in the force powers enum? also what is the value of the last number, and are you sure this code is being called (set a breakpoint on the first line of ForceStun using the debugger)

JediBantha · May 13, 2013

1.) By enums, do you mean this:

static powerEnum_t powerEnums[MAX_POWER_ENUMS] =

{ // Light powers

"absorb", FP_ABSORB,

"heal", FP_HEAL,

"mindtrick", FP_TELEPATHY,

"protect", FP_PROTECT,

"stun", FP_STUN,

// Core powers

"jump", FP_LEVITATION,

"pull", FP_PULL,

"push", FP_PUSH,

"sense", FP_SEE,

"speed", FP_SPEED,

"sabdef", FP_SABER_DEFENSE,

"saboff", FP_SABER_OFFENSE,

"sabthrow", FP_SABERTHROW,

// Dark powers

"drain", FP_DRAIN,

"grip", FP_GRIP,

"lightning", FP_LIGHTNING,

"rage", FP_RAGE,

};

2 & 3.) : *Blew my mind*

eezstreet · May 13, 2013

I'm talking about the list that has FP_SEE, FP_LEVITATION, etc in it

JediBantha · May 13, 2013

This one?

typedef enum

{

FP_FIRST = 0,//marker

FP_HEAL = 0,//instant

FP_LEVITATION,//hold/duration

FP_SPEED,//duration

FP_PUSH,//hold/duration

FP_PULL,//hold/duration

FP_TELEPATHY,//instant

FP_GRIP,//hold/duration

FP_LIGHTNING,//hold/duration

FP_SABERTHROW,

FP_SABER_DEFENSE,

FP_SABER_OFFENSE,

//new Jedi Academy powers

FP_RAGE,//duration - speed, invincibility and extra damage for short period, drains your health and leaves you weak and slow afterwards.

FP_PROTECT,//duration - protect against physical/energy (level 1 stops blaster/energy bolts, level 2 stops projectiles, level 3 protects against explosions)

FP_ABSORB,//duration - protect against dark force powers (grip, lightning, drain - maybe push/pull, too?)

FP_DRAIN,//hold/duration - drain force power for health

FP_SEE,//duration - detect/see hidden enemies

FP_REPULSE,

FP_DESTRUCTION,

FP_DEADLYSIGHT,

FP_BLIND,

FP_STUN,

FP_BREACH,

NUM_FORCE_POWERS

} forcePowers_t;

I haven't really gotten to the other new powers in the list, just finished moving my desktop back into my house...

eezstreet · May 13, 2013

I think it's limited to 16 force powers. Don't hold me to that.

JediBantha · May 13, 2013

Would changing this do any good? (cg_local.h)

#define MAX_SHOWPOWERS 18

extern int showPowers[MAX_SHOWPOWERS];

extern char *showPowersName[MAX_SHOWPOWERS];

extern int force_icons[NUM_FORCE_POWERS];

#define MAX_DPSHOWPOWERS 22

eezstreet · May 13, 2013

Yes. MAX_SHOWPOWERS should be NUM_FORCE_POWERS-5

MAX_DPSHOWPOWERS should be NUM_FORCE_POWERS-1

JediBantha · May 13, 2013

You lost me there.

eezstreet · May 13, 2013

#define MAX_SHOWPOWERS NUM_FORCE_POWERS-5

#define MAX_DPSHOWPOWERS NUM_FORCE_POWERS-1

JediBantha · May 13, 2013

Do I need to put them in manually, or make edits?

Stoiss · May 14, 2013

#define NUM_FORCE_POWERS-5

#define NUM_FORCE_POWERS-1

Like this i guess ?

eezstreet · May 14, 2013

No. You need to edit the already existing lines in order for them to look like my lines.

JediBantha · May 14, 2013

#define MAX_SHOWPOWERS NUM_FORCE_POWERS-5

extern int showPowers[MAX_SHOWPOWERS];

extern char *showPowersName[MAX_SHOWPOWERS];

extern int force_icons[NUM_FORCE_POWERS];

#define MAX_DPSHOWPOWERS NUM_FORCE_POWERS-1

If you meant this, the result I got out of it was the "too many initializers" error, causing one of the files to fail.

eezstreet · May 14, 2013

Check where it is breaking. It's one of the array definitions breaking (you need to change the entries)

JediBantha · May 14, 2013

This also happened with the original entry when I tried to add the power(s):

#define MAX_SHOWPOWERS 12

extern int showPowers[MAX_SHOWPOWERS];

extern char *showPowersName[MAX_SHOWPOWERS];

extern int force_icons[NUM_FORCE_POWERS];

#define MAX_DPSHOWPOWERS 16

When I changed the entries to 18-22, it didn't have any problems from there.
