AGB Programming Manual Rendering Functions [d15-14] OBJ Size Linked to the specification of the OBJ size for Attribute 0, the size for the OBJ Character is also specified. For each of the three OBJ shapes, you can set four sizes. OBJ Shape 00 A 8x8 01 B 16x16 OBJ Size C 10 32x32 D 11 64x64 00 Square E 16x8 F 32x8 G 01 32x16 H 64x32 I 8x16 10 J 8x32 K 16x32 L 32x64 Vertical Rectangle Horizontal Rectangle 11 Prohibited Code [d13] [d12] Vertical and Horizontal Flip Flags Allows the OBJ to be flipped horizontally and vertically. A normal display is produced by a setting of 0 and a flip display by a setting of 1. When the rotation/scaling flag ([d08] of OBJ Attribute 0) is enabled, these bits also can be used as the high-order bits of the rotation/scaling parameter selection. [d13-09] Rotation/Scaling Parameter Selection The parameters used in OBJ rotation/scaling processing are selected from the 32 parameters registered in OAM. ©1999 - 2001 Nintendo of America Inc. 67 D.C.N.
