UI Motion
Type	Base
Games used	The Incredibles

Format

A UI Motion asset begins with a 0x18-byte header which extends from xBaseAsset:

struct zUIMotionAsset : xBaseAsset
{
	uint8 cmdCount;
	uint8 in;
	uint8 pad[2];
	uint32 cmdSize;
	float totalTime;
	float loopTime;
};

Offset	Type	Variable	Description
0x08	uint8	cmdCount	Number of commands after the header
0x09	uint8	in
0x0A	uint8[2]	pad	Padding
0x0C	uint32	cmdSize
0x10	float	totalTime
0x14	float	loopTime

Following the header is a list of Commands (with a length of cmdCount). The format of each command is explained below.

Commands

There are 8 types of Commands defined:

• 0 - Move
• 1 - Scale
• 2 - Rotate
• 3 - Opacity
• 4 - AbsoluteScale
• 5 - Brightness
• 6 - Color
• 7 - UVScroll

Each command type has an 0x18-byte header:

struct zUIMotionCmdAsset
{
	uint32 type;
	float startTime;
	float endTime;
	float accelTime;
	float decelTime;
	uint8 enabled;
	// 3 bytes of padding
};

Offset	Type	Variable	Description
0x00	uint32	type	Type ID (see above)
