| Ok, well, first off I'm having some linking issues. I'll not ask you all to fix these for me (yet :P). But I am having trouble. It appears that the following code is hanging the entire mud up, making me have to restart:
for ( asteroid = ship->starsystem->first_asteroid; asteroid; asteroid = asteroid->next_in_system)
{
if (abs(ship->vx - asteroid->x) < 1 &&
abs(ship->vy - asteroid->y) < 1 &&
abs(ship->vz - asteroid->z) < 1 )
{
ship->collision = asteroid->maxhp;
asteroid->collision = ship->maxhull;
}
}
The only conclusions I've come by is that the asteroid doesnt have an x/y/z. Anyways, I'd ask that you look over http://ew.xidus.net/code/3.0a.c and http://ew.xidus.net/code/asteroids.h for the actual asteroid code. Perhaps you could find any errors in the linking I've got. |

| | By the way, this only happens after an asteroid has been destroy and put back in the system. The linking errors are within starsystems because if I go to my Terra star system EVERY asteroid is in the list and display on look and radar. However, you cannot target or fire at them. |

| | Something tells me its extract_asteroid. I don't think the unlink is needed. |

| Hmm, perhaps you all can spot something wrong with this function.
/*
* Extract the asteroid from a starsystem
*/
bool extract_asteroid( ASTEROID_DATA *asteroid )
{
SPACE_DATA *starsystem;
starsystem = asteroid->starsystem;
if ( asteroid == NULL || starsystem == NULL )
return FALSE;
if ( starsystem != NULL )
{
if ( starsystem->last_asteroid == asteroid )
starsystem->last_asteroid = asteroid->prev_in_system;
if ( starsystem->first_asteroid == asteroid )
starsystem->first_asteroid = asteroid->next_in_system;
if ( asteroid->prev_in_system )
asteroid->prev_in_system->next_in_system = asteroid->next_in_system;
if ( asteroid->next_in_system)
asteroid->next_in_system->prev_in_system = asteroid->prev_in_system;
}
UNLINK( asteroid, starsystem->first_asteroid, starsystem->last_asteroid, next_in_system, prev_in_system );
asteroid->starsystem = NULL;
return TRUE;
}
Thanks, hopefully we'll find something. I think it has to do with the UNLINK. Perhaps some of what it does is already taken care of above? |

| | ::sigh:: Posting before I mess with it myself sure makes me look stupid. It appears I had my loop wrong, and was referencing to the master asteroid list (asteroid->next) rather than the individual list of each starystem (asteroid->next_in_system) and I am actually having no linking issues. However, I would still like to know about extract_asteroid. I'll go conjure some other problem for oyu all to solve. |
