Quote from B_squo~

This is my own take at a "impossible CPUs"-type of mod. This features CPUs instantly throwing random items towards the player, plus them always following the player if near enough to them, even if they have to exit their usual paths.

This code hasn't been tested very much, only on Dolphin...
You should be able to combine this with other CPU-related codes, (such as codes that change the CPU's speed) to achieve even crazier results.

I recommend using an item delimiter code such as this one for the best experience: https ://mariokartwii.com/showthread.php?tid=259

Alternative version. Just like above, except that you can choose what item CPUs will throw. XX is the item ID (see "Item Box number" here: https ://wiki.tockdom.com/wiki/List_of_Identifiers#Items)

=== Documentation ===
This code switches the regular CPU race "control" by the one used in the N64 DK's Jungle Parkway competition, which allow them to equip an item without touching item boxes, nor requiring any item hack.

Normally, this control only allows CPUs to throw single bananas when near enough the player, and at certain semi-random intervals. This code modifies that so that the item equipped by the CPU is randomized every frame, and to remove the delay in-between each item throw.

As for the "CPUs following the exact path of the player" part, it was made by forcing the game into calling the function responsible for following the player when they have a Mega Mushroom or Thundercloud, with a modified, larger radius.

Collection of Codes with explanation:

Code:

    When initializing the match, create the N64 DK's Jungle Parkway competition CPU control instead of the race one. This is done for both the race control and the battle control.

04731cb0 4bffdb51

    Makes the "isNearPlayer" function associated to the N64 DKJP competition CPU control always return true, in order to allow CPUs to throw items no matter where they are.

    Remove the delay time in between item throws

0472fcd8 60000000
0472fed0 60000000

    Small function that randomizes the item given to the player from items ID 0 to 6. The hook overwrites a call to a "item limit not reached" function, which we won't need for the mod.

    CPUs will only follow player 0 (the first human player)

    Set the XZ size of the CPU follow radius. If the player is inside the radius limited by the CPU's position and this value, then the CPU will start chasing the human player.

    Ignore Y component of the CPU follow radius
