bow and arrow problem

[MDave]

Hi there, I've had this problem for months and I still don't know how to fix it I have made a bow and arrow type weapon, and depending on its charge animation frame, shoots an arrow at a specific velocity. What the problem is, is soon after loading a map, and charging up an arrow, it crashes the server. But if I wait for a while, its safe to use it. It's been driving me nuts

Below is the code from weapons.qc

And this is from player.qc

If this isn't enough information, I can provide a link to all my .qc files. I've got a few more bugs to handle too, but it might be asking for much to ask for help on those too

Thanks for reading.

Well, for one thing, you should not be using 'other' in Arrow_Explode (since you are using it as a delayed think function). Do 'self.enemy = other;' in arrow_f_touch(), and use that instead. Don't know if this is what is causing your crash though. Are you getting a useful error message, or is the crash completely mysterious?

Nothing to add, just wanted to point out Inside3d's own QC Pastebin - http://www.inside3d.com/pastebin.php

Be nice to see it used for something other than just keeping the spambots occupied =)

scar3crow, thanks, I must of missed it somehow

Thanks for the tip!

Ahh sorry, forgot to post the error message:

"CALL0 14421(?]
: W_WeaponFrame
: PlayerPostThink
(NO FUNCTION)
NULL function
Host_Error : Program error"

EDIT: After further testing, it only seems to happen when you change level, and not when you use the map command or start a new game.

[Sajt]

Can you post the contents of W_WeaponFrame?

Also, what QCC compiler are you using? I think many of them (FTEQCC included) have an evil habit of warning when they should error. For example, you could call a nonexistant function (perhaps misspelled) and it would still compile. Are you getting any qcc compiler warnings?

[FrikaC]

Can you post your modified W_Attack also?

[MDave]

I'm using Frikqcc.

I posted the code in the pastebin:

http://www.inside3d.com/pastebin.php?ac ... ow&id=4491

and W_Attack here.

http://www.inside3d.com/pastebin.php?ac ... ow&id=4492

I apologise for the somewhat messy code, I'm not really a coder by nature.

[FrikaC]

player_arrow1 I assume is your new animation sequence. Post that code please? I suspect the error has to deal with the next function in the state macros. If there's a spelling or typo error in the name(s) of the functions in the state macros you can get a NULL function when it tries to call it.

Dunno why FrikQCC didn't error if that is the case however, which version of frikqcc are you using? (wish I never did all those hacks to make Nehahra compile and never reverted them, damnit)

[MDave]

I posted the player_arrow1 code in my first post

http://pastebin.com/m10c639c4

I'm using version 2.7.

[FrikaC]

oh so you did. I was expecting an anim....Hmm.

Code: Select all

    if (self.aflag == 1)         // make sure to fix downed gun

    {
        self.aflag = 0;         // no longer down

        self.think1();          // function called to raise gun

        self.think1=SUB_Null;   // reset pointer

    }

Just a guess - are you properly setting up self.think1 on changelevel? That could be why you're getting a null function error, if you're calling self.think1() and you haven't set it to anything yet (ie another weapon hasn't set it to SUB_Null/anything else yet).

[MDave]

Thanks, that seems to have fixed it! I added other.think1=SUB_Null; in the 'execute_changelevel' function's while loop.

Many thanks!

I can get onto my next problem then.

How can I make my arrows and remote mines not stick to doors/platforms/trains? And fall down to the floor instead?

[MDave]

Damn, I thought It was fixed but I'm getting the error again

[MDave]

Ok, I fixed it for good this time, just added:

Code: Select all

        self.aflag = 0;                 // we'll say gun isn't down yet
        self.think1=SUB_Null;         // so we don't need to raise it



before player_arrow1; in W_Attack

I also fixed my arrows and remote mines problem. Almost glitch free now! Now I just need to figure out the best way to stick remote mines onto players/monsters properly.
