Blueprint Alignment

This mod allows enforcing a certain alignment for blueprints, e.g. it can enforce that a certain blueprint is always build on a 8x8 grid. When deploying a blueprint, the mod will check whether the blueprint is properly aligned and shift it to the nearest aligned position otherwise. Note that when building without SHIFT, the blueprint will only be built if it can be built both at the position where you are trying to build it and at the properly aligned position.

Setting the alignment

The alignment can be set using the GUI. The blueprint alignment GUI can be opened whenever you are editing a blueprint by clicking on the blueprint icon in the upper bar.

You can set the following properties:

• Alignment X/Y: The alignment of the blueprint. Specifying 8 for both X and Y will align the blueprint on a 8x8 grid.
• Center X/Y: The position of the point in the blueprint which will be aligned. This is important if the blueprint is rotated. If "Store as label" is disabled, a cross will be shown in the blueprint where the center is.
• Offset X/Y: This is a global offset which will be aligned to the position where the blueprint will be built.
• Store as label: When this checkbox is enabled, the alignment properties will be stored in the blueprint label. Otherwise (the default) the properties will be stored in a special entity in the blueprint.

Mod settings

There is a per-savegame setting for a global X/Y offset. This offset will be applied to all blueprints. (This can be useful if you want to share blueprints across savegames but the savegames have used different starting points.) The default value for the alignment is 1, which means that the
center of a rail can be aligned to an even number. (If the global offset is even, the corners of straight rails can be aligned.)

Example

The following blueprint contains a roboport and 5 power poles which will automatically be aligned properly (the supply areas of the roboports will touch):
