| Here is an updated list of the variables used by each object; looking at the ASM has really helped with this: (f/p) is a floating-point value. 0x?? or 0x???? are hexadecimal values. [0x00] 0x001800 Always that value, should not be changed as it marks the start of an object structure. [0x02] 0x0025 Collection of bits that alters how the object behaves in relation to the camera. 0x25 causes the object to always face the camera as is the case of the 2D objects like trees and other objects so that it appears 3D (billboarding), however it can be used with 3D objects. 0x21 is used for true 3D objects so the object isn't forced to always face the camera since rotating the camera will show other parts of the object. [0x04] 0x8030B0B8 Usually pointer to the previous object. If this is the first object, it will point to the last object. [0x08] 0x8030B578 Usually pointer to the next object. If this is the last object, it will point to the first object. [0x0C] 0x80386A20 Always equals this value, points to a structure that contains variables which affect all the objects. [0x10] 0x00000000 ? [0x14] 0x80195084 Pointer to the object's graphics structure. [0x18] 0x01 Use graphics flag: =0x00 don't display object's graphics, =0x01 do display object's graphics. [0x19] 0x01 Appears to have no effect on the object; usually equals 0x01 if [0x18]=0x01, sometimes is 0xFF. [0x1A] 0x0000 ? [0x1C] 0x00000000 ? [0x20] 0xC4A6A000 (f/p) Some form of coordinate? [0x24] 0x4431C000 (f/p) Some form of coordinate? [0x28] 0x44EB2000 (f/p) Some form of coordinate? [0x2C] 0x3F800000 (f/p) X size modifier (scaling value). [0x30] 0x3F800000 (f/p) Y size modifier (scaling value). [0x34] 0x3F800000 (f/p) Z size modifier (scaling value). [0x38] 0x00000000 ? [0x3C] 0x80060030 Pointer to the object's animation structure; if zero, object is not animated. [0x40] 0x00000000 ? [0x44] 0x00000000 ? [0x48] 0x00010000 ? [0x4C] 0x00000000 ? [0x50] 0x00000000 ? [0x54] 0x3F751000 ? [0x58] 0xC2D2C670 (f/p) Some form of coordinate? [0x5C] 0xC444B1C0 (f/p) Some form of coordinate? [0x60] 0x8030FA58 Pointer to object ? [0x64] 0x8030F598 Pointer to object ? [0x68] 0x8030F7F8 For objects that follow another (e.g., coin in a Boo) this is a pointer to the object to follow. [0x6C] 0x00000000 ? [0x70] 0x00000000 ? [0x74] 0x01 ? [0x75] 0x01 Determines if the object is active: 0x00=remove the object (the structure remains), 0x01=continue using this object. [0x76] 0x0001 ? [0x78] 0x803194B8 Pointer to object collided with (usually pointer to Mario's object structure even before collision has occurred)? [0x7C] 0x00000000 ? [0x80] 0x00000000 ? [0x84] 0x00000000 ? [0x88] 0x00000000 ? [0x8C] 0x0000 [0x8E] 0x0001 How much object reacts to Mario (not used by some behaviours) 0x0001=Do not react to Mario. 0x0009=? 0x0449=Follow Mario. 0x2041=? 0x2049=Respond to Mario. 0x20C9=? 0x2449=Rotate to face Mario.

[0xC4] 0x00000000 X collision rotation? [0xC8] 0xFFFFBA00 Y collision rotation? [0xCC] 0x00000000 Z collision rotation? [0xD0] 0x00000000 X object rotation. [0xD4] 0xFFFFBA00 Y object rotation. [0xD8] 0x00000000 Z object rotation. [0xDC] 0x00000000 ?
