LUA ERROR: Lua Function sys_base_impact: base/system.lua:63: Invalid instance 1064

I thrown a shuriken at a mummy inside "Creature Cavern" in DM.
They had no exvar or inventory whatsoever.
Id : RTC_2186, RTC_2187 and RTC_2188 in dm/dungeon.lua

Fixed.

The problem was that it was trying to put the projectile in the monster's inventory (getting "stuck," as it were), but the monster was already dead. This was happened due to Lua using floating point numbers internally.

The code was, roughly:

Code: Select all

damage = calculate_damage()
hp = hp - damage
dsb_set_hp(monster, hp)
if (hp > 0) then
  -- put projectile in monster's inventory
end

So, if it ended up that hp was between 0 and 1, it would evalulate down to 0 for the dsb_set_hp but it would be > 0 and try to get put in the inventory.
