I wonder mutation conlfict number meaning

[newbee_band]

tatic const int conflict[][3] =
{
#if TAG_MAJOR_VERSION == 34
{ MUT_STRONG_STIFF, MUT_FLEXIBLE_WEAK, 1},
#endif
{ MUT_STRONG, MUT_WEAK, 1},
{ MUT_CLEVER, MUT_DOPEY, 1},
{ MUT_AGILE, MUT_CLUMSY, 1},
{ MUT_SLOW_HEALING, MUT_NO_DEVICE_HEAL, 1},
{ MUT_ROBUST, MUT_FRAIL, 1},
{ MUT_HIGH_MAGIC, MUT_LOW_MAGIC, 1},
{ MUT_WILD_MAGIC, MUT_SUBDUED_MAGIC, 1},
{ MUT_CARNIVOROUS, MUT_HERBIVOROUS, 1},
{ MUT_SLOW_METABOLISM, MUT_FAST_METABOLISM, 1},
{ MUT_REGENERATION, MUT_SLOW_HEALING, 1},
{ MUT_ACUTE_VISION, MUT_BLURRY_VISION, 1},
{ MUT_FAST, MUT_SLOW, 1},
{ MUT_REGENERATION, MUT_SLOW_METABOLISM, 0},
{ MUT_REGENERATION, MUT_SLOW_HEALING, 0},
{ MUT_ACUTE_VISION, MUT_BLURRY_VISION, 0},
{ MUT_FAST, MUT_SLOW, 0},
{ MUT_BREATHE_FLAMES, MUT_SPIT_POISON, -1},
{ MUT_FANGS, MUT_BEAK, -1},
{ MUT_ANTENNAE, MUT_HORNS, -1},
{ MUT_HOOVES, MUT_TALONS, -1},
{ MUT_TRANSLUCENT_SKIN, MUT_CAMOUFLAGE, -1},
{ MUT_MUTATION_RESISTANCE, MUT_EVOLUTION, -1},
{ MUT_ANTIMAGIC_BITE, MUT_ACIDIC_BITE, -1},
{ MUT_HEAT_RESISTANCE, MUT_HEAT_VULNERABILITY, -1},
{ MUT_COLD_RESISTANCE, MUT_COLD_VULNERABILITY, -1},
{ MUT_SHOCK_RESISTANCE, MUT_SHOCK_VULNERABILITY, -1},
{ MUT_MAGIC_RESISTANCE, MUT_MAGICAL_VULNERABILITY, -1},

What is different between 1 , 0 , -1 ?

Would you explain with an example?

It seems a bit complicated, but the code that uses these numbers is here.

  Code:

// Tries to give you the mutation by deleting a conflicting
// one, or clears out conflicting mutations if we should give
// you the mutation anyway.
// Return:
//  1 if we should stop processing (success);
//  0 if we should continue processing;
// -1 if we should stop processing (failure).

I think basically the numbers correspond to ways of resolving the conflict in the simplest case: "1" means that one mutation will lower the level of the other (the mutations are on the same scale, and are like the negations of each other), "0" means that one will be removed in order to actually add the other, and "-1" means that the two conflict but the conflict can't normally be resolved. It looks like there's quite a bit more to it than this, especially for the -1 case, depending on the source/type of the mutation (gods, transient mutations, etc), but I haven't tried to parse out the details.

The return values don't exactly correspond to the entries in conflict[], though they are related.

deleted inaccurate explanations

Edit: There was a bug with the order, now fixed; and I added a comment explaining the meaning of the numbers in more detail. That explanation is better than what I had written in this message, so please read that commit for details on what the conflict levels mean.
