Object List file

Object List files are configuration files used in the Windows PC version of LEGO Rock Raiders to designate the starting locations of Rock Raiders, buildings, vehicles, creatures, building materials, webs, and the game camera within levels. They use the filename extension ".ol" by default, though they're essentially just text files. Each level's Object List is linked to in that level's section in Lego.cfg using the code OListFile, and is by default located within that level's folder.

Formatting

Each entry in an Object List designates the coordinates and facing angle of a certain object. Buildings are often placed with the main part of the construction in the center of a block (ex: 7.5, 8.5), with the Power Path part of the construction pointing towards the facing angle. The facing angle or heading is in degrees in typical compass format, with 0 degrees pointing to the top of the map, and 90 degrees pointing to the right side of the map.

An Object List can have a maximum of 200 entries; going over this limit exceeds its memory pool, causing the level to crash^[verify]. While the allotted name of an object can be anything, it's typically in the format Object# (using a number in place of #) to keep track of the amount of objects used. Any special objects that are used in script are referred to using this allotted name.

If an Object List doesn't have a camera defined, the game will crash while loading at startup. If there is a camera but no non-hidden controllable units, the game will run up through the briefing for that mission, at which point it will softlock.

Example

Lego* {

	Object1 {
		type	[ObjectName]
		xPos	[X-Coordinate Location]
		yPos	[Y-Coordinate Location]
		heading	[Facing Angle]
	}
 
	Object2 {
		type	[ObjectName]
		xPos	[X-Coordinate Location]
		yPos	[Y-Coordinate Location]
		heading	[Facing Angle]
	}

}

Modding

Object List files are unencrypted and can easily be edited with even Notepad.
