  • 0x+110 (ai5) Unknown, always 1 (SMBX forces it to be 1) [Related to 2-player mode]

0x+108 (ai4) Details

  • The timer is mostly random
  • However, repeatedly setting the values based on a range can modify the rate at which hammers are thrown. For example:
if tableOfBowser[1]:mem(0x108, FIELD_DFLOAT) < 15 then
  tableOfBowser[1]:mem(0x108, FIELD_DFLOAT, 15);
end
if tableOfBowser[1]:mem(0x108, FIELD_DFLOAT) > 15 then
  tableOfBowser[1]:mem(0x108, FIELD_DFLOAT, 15);
end

(where tableOfBowser is a table of the active SMB1 Bowsers returned by `NPC.get(200, -1)`)

  • The internal ai4 equals to this C++ pseudocode
ai4 = ai4 + 1
if(rand() * 40 + 80 >= ai4)  // random number from 80 to 120
{
  if(rand() * 100 <= 40 && ai4 % 16 == 0)  // random number from 0 to 100
  {
    <hammer spawn code>
  }
}
else
{
  if(rand() * 50 + 300 < ai4){  //random number from 300 to 350
    ai4 = 0
  }
}
  • Note that in the Lua code, we set the value to 15. In the C++ code, the random spawn rate is based on a modulus of 16. This is due to the fact that when setting the value in Lua, it is automatically incremented to 1 above of what is set.
