Added circle, cylinder and sphere buildmodes. Refactored buildmodes to use hierarchy classes, much less code duplication. Added support for multiple options per build mode.

Added alternative placement key (ctrl) that toggles between first two actions of first option. Fixed crash when placing ladders.
Branching, version update.

Author	SHA1	Message	Date
Christian Knaapen	c16a924bb9	Added circle, cylinder and sphere buildmodes. Refactored buildmodes to use hierarchy classes, much less code duplication. Added support for multiple options per build mode. Added alternative placement key (ctrl) that toggles between first two actions of first option. Fixed crash when placing ladders.	2019-12-23 12:39:08 +01:00
Christian Knaapen	3718492495	Branching, version update.	2019-12-04 15:16:21 +01:00
Christian Knaapen	3e5eb4cb30	Fix randomizer bag consuming an extra block in some cases.	2019-11-17 19:48:33 +01:00
Christian Knaapen	2c6b58ddc6	Fixed issue #45 : Can't break blocks in survival mode if breakFar=false.	2019-07-09 02:23:35 +02:00
Christian Knaapen	3921a0b70b	Fixed issue #43 : Duplicating blocks in survival (undo/redo not working in normal mode). Fixed QuickReplace in normal mode not placing any blocks. Fixed blockstates sometimes changing on undo/redo. Now clearing UndoRedo stacks on clientside when changing dimension or logging out. Breaking mirror/array in survival is now possible again. Breaking blocks in survival in any buildmode is now possible (previously only in normal mode unless instabreaking was enabled). Still with limited (vanilla) reach.	2019-07-09 02:11:32 +02:00
Christian Knaapen	11cd20c3d3	Fixed QuickReplace in normal mode not placing any blocks.	2019-07-08 22:54:33 +02:00
Christian Knaapen	4ce8b1e927	Fixed issue #23 dank/null compat only uses one block at a time regardless of how many are placed.	2019-07-06 13:17:08 +02:00
Christian Knaapen	0485e6c888	README.md created online with Bitbucket	2019-07-03 10:26:25 +00:00
Christian Knaapen	89057356df	Changed MaxBlocksPerAxis and MaxBlocksPlaced formulas. Now allows placing of 60x60 floors and walls with reach upgrade 3 in survival.	2019-06-05 20:02:37 +02:00
Christian Knaapen	a7ac229242	Fixed issue #37 Visual Glitch when destroying blocks	2019-05-17 16:26:19 +02:00
Christian Knaapen	b2ee5dbc04	Fast breaking in Normal+ mode in addition to fast building. Fixed issue #36: Having issues with some features with a Sponge Forge Server. Messed with shader to try and fix some issues.	2019-05-12 11:52:11 +02:00
