The Filler is a machine to fill whole areas with blocks. It needs to be placed in front of a Landmark to fill the area the Landmark is describing.
The fastest and cleanest way to run most buildcraft machines that need to manipulate large areas is to stick an Energy Link on top of the machine, and a HV Solar Array on top of the Energy Link . For nightime operation stick a MFSU between the Energy Link and the HV Solar Array. A setup like this requires no fuel, no chained engines, and will run extremely fast (placing several blocks per second).
Right-clicking on a Filler brings up the Filler interface. The top 3x3 area is for a Filler pattern, and the resources area is where you place the materials to build with. There are 6 patterns that can be used. Patterns are made by placing Bricks and/or Glass in the top 3x3 area. When there is a valid pattern in the Filler, the pattern icon will be visible in the small space in the top of the interface, and on the sides of the Filler. The lights on top of the Filler will also have turned green.
A Filler will fill in water blocks, but will not fill in lava or Oil blocks at all. Sand or Gravel can be used in the Filler to fill in lava or Oil, due to gravity affecting them. When the Filler has finished its task, the lights will turn red again to indicate that it is finished. To start it working again on the same area, just remove and replace one of the bricks or glass from the pattern. A pick is needed to retrieve a Filler once placed.
- Care should be taken when clearing areas using the Flatten or Clear patterns, as the cleared blocks will sit on the ground for you to collect, easily piling up and causing lag.
- The filler seems buggy when used in multiplayer games when the location outlined starts with a negative X or Y coordinate ending in positive coordinates.
When placed, this gui will open:
Fill pattern: Fills the area with blocks.
Clear pattern: Removes all blocks in the area.
Stair pattern: Creates a staircase with 1 block high steps.
Box pattern: Walls, ceiling and floor.
Flatten pattern: Clears the area, and fills in holes in the the layer underneath the area.
Pyramid pattern: Creates a pyramid inside the area.
Like the Builder , upon completion the Filler may leave behind the yellow construction frame. This is a common glitch. To get rid of the frame you have to disconnect and reconnect.
