Greg's SG Craft

This is a mod for the game Minecraft. Currently it gives you SG-1 style stargates. In the future, it may include other things from the SG-1 universe.



This is a Forge-based mod, so if you haven't done so already, you will need to install Forge. See the Download section below for recommended versions. The contents of the downloaded zip files for these needs to be copied into your minecraft.jar file.


SG Craft has been tested with the following versions of Minecraft and Forge. It may or may not work with other versions.

Change History

Version 1.13.3
Fixed collision boxes of naquadah ore and naquaday alloy block.
Version 1.13.2
Prevented power units from causing unnecessary chunk updates.
Fixed 9-chevron engagement sequence.
Added config option for whether to move chevrons when base camouflage present.
1.7.10: Fixed Open Computers interfaces not being recognised by computers.
Version 1.13.1
Fixed client crash on opening stargate GUI in multiplayer.
1.10.2: Fix incorrect sounds in multiplayer.
Version 1.13.0
Updated for Minecraft 1.10.2.
The addressing scheme for dimensions has changed. Dimension addresses are now assigned dynamically, so dimension numbers are no longer restricted to -648 to 647 (there is a limit of 1296 different dimensions containing gates, but that's very unlikely to be reached). Also, the dimension symbols are hashed with the rest of the address, so you can't easily tell which dimension a gate is in from its address. As a result of these changes, if you have converted a world from a previous version, the reported addresses of existing gates will have changed in the last two characters. You will still be able to dial them using the old addresses, however.
Order of chevron engagement is now more authentic.
Improved repositioning of chevrons in response to base camouflage.
Accidental breaking of a connected gate is prevented in creative mode.
Fixed: Crash on casting a fishing line through a gate. (Can't fish through the gate, though, sorry.)
Fixed: Extra leash dropped when leashed entity passed through a gate.
Version 1.12.1
German language update from Timmy94W.
Version 1.12.0
1.8.9: Added IC2 power unit.
Version 1.11.3
Fix infinite recursion when addOresToExistingWorlds enabled.
1.7.10: Prevent ArrayIndexOutOfBoundsException from Maritech world generation.
Version 1.11.2
Fixed a debugging stament that could cause a crash when removing a DHD.
Made setting secondsToStayOpen to 0 work as advertised.
1.8.9: Added German language file.
1.8.9: Prevented crash when inappropriate items placed in camouflage slots.
Version 1.11.1
1.7.10: Fix index out of bounds in textureStitchEventPre when used by some other mods
Version 1.11.0
Backported to MC 1.7.10.
Stargates will now preferentially draw power from a power unit instead of using naquadah if both are available.
Generic recipe now available for RF power unit when Thermal Expansion not installed.
SG Craft items now have their own creative tab.
Computer API calls no longer raise exceptions on error, but return nil and an error message. This brings the API more into line with Lua programming conventions and avoids some incompatibilities between Computercraft and Open Computers concerning formatting of error messages. See the note on Error Handling in the documentation for a way to adapt your existing code.
1.7.10: Added German language file (contributed by Timmy94W).
1.8.9: Computercraft and Open Computers interfaces added.
Internals (1.8.9): Changed the names used for facings in the block states to make them more intuitive -- blocks placed when the player is facing north now show as oriented "north" rather than "east". Metadata values remain the same for compatibility with existing worlds, although this means they are probably different from what most vanilla blocks use.

If a dimension becomes unloaded, any open stargate connections to it should now be automatically closed.
Breaking a ComputerCraft stargate interface should no longer be able to crash the server.
The chunkLoadingRange config setting can now be set to -1 to prevent stargates from keeping any chunks loaded. However, this may result in undesirable effects such as connections closing immediately upon leaving a dimension, so use with discretion.
Version 1.9.3
Fixed Computercraft stargate interface not working when OpenPeripheral installed.
Version 1.9.2
Restored sending of DimensionRegisterPackets for MCPC+.
