Priority of Link's actions in OoT

Here's something interesting I learned from decomp which shows the priority of many of link's actions.

These list of numbers determine which action functions to run and which order to run them in while Link is in certain states in the game. It will stop after one succeeds. This means if you perform 2 actions on the same frame it will choose the earlier one in the list and perform that one. Ignore the negatives on numbers. Negatives are just used to determine if it is the last function.

D_808543E0[] = { 13, 2, 4, 9, 10, 11, 8, -7 }: Stand while Targeting with shuffling feet (holding shield or targeting an enemy)
D_808543E8[] = { 13, 1, 2, 5, 3, 4, 9, 10, 11, 7, 8, -6 }: Standing while targeted
D_808543F4[] = { 13, 1, 2, 3, 4, 9, 10, 11, 8, 7, -6 }: Sidewalk slowly
D_80854400[] = { 13, 2, 4, 9, 10, 11, 8, -7 }: Backwalk or Stutter step
D_80854408[] = { 13, 2, 4, 9, 10, 11, 12, 8, -7 }: Sidewalk fast, and an unknown action
D_80854414[] = { -7 }: Turn in place, leaving water
D_80854418[] = { 0, 11, 1, 2, 3, 5, 4, 9, 8, 7, -6 }: Standing while untargeted, and an unknown action
D_80854424[] = { 0, 11, 1, 2, 3, 12, 5, 4, 9, 8, 7, -6 }: Walk while untargeted
D_80854430[] = { 13, 1, 2, 3, 12, 5, 4, 9, 10, 11, 8, 7, -6 }: Walk forward while targeted
D_80854440[] = { 10, 8, -7 }: something to do with z-targeting
D_80854444[] = { 0, 12, 5, -4 }: Swimming

The game checks if each action below is doable in a separate function, and the functions might do more than I wrote:
0 = func_8083B998 = Use C-up / Use Cutscene item or First Person item
1 = func_80839800 = Open Door
2 = func_8083E5A8 = Grab Actor
3 = func_8083E0FC = Mount Epona
4 = func_8083B644 = Speak / Check something
5 = func_8083F7BC = Enter Crawlspace or lift heavy block
6 = func_8083C1DC = Untargeted Roll
7 = func_80850224 = Slash sword / Spin attack
8 = func_8083C544 = Charge Spin Attack
9 = func_8083EB44 = Drop/Throw Held Actor
10 = func_8083BDBC = Targeted roll / Jumpslash
11 = func_8083C2B0 = Shield
12 = func_80838A14 = Climb Ledge
13 = func_8083B040 = Use Cutscene item or First Person item

As you can see, "Backwalk", "Sidewalking fast", and "Stand while Targeting with shuffling feet" do not run function 1 or 3, so that is why you cannot open Doors or mount Epona while doing one of those actions (even though the A button says Open or Climb).

Some other things it explains:
-why you can't climb ledges while targeting with shield or sidewalking slowly (but can while sidewalking quickly)
-why opening doors is prioritized over grabbing actors such as bombs
-why if you press shield and open a door on the same frame, link will open the door if you are targeted, but shield if you are not
-why you can't c-up while targeted, but when you can, it is prioritized over almost everything
-and more...


More decomp info:

func_80837348 is the function which loops one of these arrays. It stops after a negative number or if one of these functions returns a 1.

This is the list of functions from 0 to 13:
static s32 (*D_80854448[])(Player* this, GlobalContext* globalCtx) = {
    func_8083B998, func_80839800, func_8083E5A8, func_8083E0FC, func_8083B644, func_8083F7BC, func_8083C1DC,
    func_80850224, func_8083C544, func_8083EB44, func_8083BDBC, func_8083C2B0, func_80838A14, func_8083B040,
};
