Overview

objflow.byaml is a BYAML file found in the directory /content/data of the Wii U version of Mario Kart 8. It contains information about animations, hitboxes, object IDs, and many others. The objflow's parameters do not apply to any .kcl files that objects use.

Object Values

These values are assigned to each object, through the element <value>. The attributes and their functions are listed below. Functions marked as gray are unknown/unsure.

Name	Function
AiReact	CPU reactions to objects. For example: ignore (decorations), avoid (obstacles), or collect (coins).
CalcCut	Can be true or false.
Clip	Culling of an object. Can be true or false.
ClipRadius	Distance that the culling takes affect on.
ColOffsetY	Unknown.
ColShape	Shape of the collision of the object. Is mostly an integer.
DemoCameraCheck	Can be true or false.
LightSetting	Unknown.
Lod1	Distance needed away from object for Lod1 to load.
Lod2	Distance needed away from object for Lod2 to load.
Lod_NoDisp	Distance needed away from object to unload.
MgrId	"Mgr" usually means "Manager", which controls an object.
ModelDraw	Defines if the object has a model or not.
ModelEffNo	Sseems to be related to if an object has an "_FX" variant in the mapobj folder.
MoveBeforeSync	Defines if the object moves/animates before the countdown. Can be true or false.
NotCreate	Defines if the object spawns every time in their starting position, if they get displaced as pylons. Can be true or false.pylons
ObjID	Defines what object it is.
Offset	Height offset from the muunt point's Y position.
Origin	Unknown.
PackunEat	Defines if the Piranha Plant item will bite at the object.
PathType	Unknown.
PylonReact	Unknown.
VR	Defines if the object is a skybox.

Object Hitbox Size

<Colsize> defines the collision size for the object. It has X, Y and Z values that can be defined.

Item Behavior when touching Object

<Item type> lists 13 values in an array. They dictate what the object does to each item when it collides with it. Each index in the array corresponds to an item.

Value	Function
0	Unknown.
1	Unknown.
2	Unknown.
3	Unknown.
4	Unknown.
5	Unknown.
6	Unknown.
7	Unknown.
8	Unknown.
9	Unknown.
10	Unknown.
11	Unknown.
12	Unknown.

The values assigned to each index determine what happens to the kart when touching the object, they are as follows:

Caption text

Value	Description
0	Item ignores/goes through object.
1	Item treats object as wall (bounces off of it)
2	Item treats object as player (activates/gets destroyed)

Object Behavior when touching Item

<ItemObj type> lists 12 values in an array. They dictate what the item does to each object when it collides with it. Each position in the array corresponds to an item.

Value	Function
0	Unknown.
1	Unknown.
2	Unknown.
3	Unknown.
4	Unknown.
5	Unknown.
6	Unknown.
7	Unknown.
8	Unknown.
9	Unknown.
10	Unknown.
11	Unknown.
12	Unknown.

Vehicle Behavior when touching Object

<Kart type> lists five entries in an array. They dictate what happens to the vehicle when it touches the object. Each index in the array corresponds to what state the vehicle is in when touching the object.

Index	Vehicle State
0	Normal.
1	In a boost.
2	In a Star.
3	In a Bullet Bill.
4	In a Boo.

The values assigned to each index determine what happens to the kart when touching the object, they are as follows:

Caption text

Value	Description
0	Goes through the object.
1	Low speed; goes through object. High speed; treated like hitting a wall(?)
2	Treated like hitting a wall.
3	Treated like hitting a wall.(?)
4	Kart is spun out, but goes through the object.
5	Kart is spun out
6	Low speed; goes through object. High speed; kart is spun out
7	Kart is spun out, but goes through the object. Kart has burning effects applied.
8	Kart is spun out
9	Kart is spun out, but goes through the object. Kart has electric effects applied.
10	Low speed; wall. High speed; kart is spun out.
11	Kart gets flipped backwards once.
12	Kart gets flipped backwards once.
13	Kart gets flipped sideways once.
14	Low speed; wall. High speed; Kart gets flipped sideways once.
15	Kart gets flipped backwards twice.
16	Kart gets squished.
17	Treated like hitting a wall.
18	Kart is given a spin boost, but goes through the object.
19	Kart is given a coin boost.
20	Kart is given a boost panel boost.
21	Kart gets flipped backwards once, but goes through the object.
22	Treated like hitting a wall.
23	Kart is given a spin boost.
24	Screen shakes, can go through object.

Object Behavior when touching Vehicle

<KartObj type> lists four entries in an array. They dictate what happens to the object when a vehicle collides with it. Each position in the array corresponds to what state the vehicle is in when touching the object.

Value	State
0	Normal.
1	In a boost.
2	In a Star.
3	In a Bullet Bill.
4	In a Boo.

Object Label

<Label type> is the unique name of the object. It is also used for objects that share a base model but use different textures (i.e. multicolored Toads). The game will uses the object label to find the appropriate _Alb texture to use.

Model Name

<ModelName type> lists which model should be used if the .bfres inside the ResName folder has multiple models inside.

Resource Name

<ResName> points to the object's resource folder in the mapobj directory .
