* Nodebox: Allow nodeboxes to "connect"Auke Kok2016-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We introduce a new nodebox type "connected", and allow these nodes to have optional nodeboxes that connect it to other connecting nodeboxes. This is all done at scenedraw time in the client. The client will inspect the surrounding nodes and if they are to be connected to, it will draw the appropriate connecting nodeboxes to make those connections. In the node_box definition, we have to specify separate nodeboxes for each valid connection. This allows us to make nodes that connect only horizontally (the common case) by providing optional nodeboxes for +x, -x, +z, -z directions. Or this allows us to make wires that can connect up and down, by providing nodeboxes that connect it up and down (+y, -y) as well. The optional nodeboxes can be arrays. They are named "connect_top, "connect_bottom", "connect_front", "connect_left", "connect_back" and "connect_right". Here, "front" means the south facing side of the node that has facedir = 0. Additionally, a "fixed" nodebox list present will always be drawn, so one can make a central post, for instance. This "fixed" nodebox can be omitted, or it can be an array of nodeboxes. Collision boxes are also updated in exactly the same fashion, which allows you to walk over the upper extremities of the individual node boxes, or stand really close to them. You can also walk up node noxes that are small in height, all as expected, and unlike the NDT_FENCELIKE nodes. I've posted a screenshot demonstrating the flexibility at http://i.imgur.com/zaJq8jo.png In the screenshot, all connecting nodes are of this new subtype. Transparent textures render incorrectly, Which I don't think is related to this text, as other nodeboxes also have issues with this. A protocol bump is performed in order to be able to send older clients a nodeblock that is usable for them. In order to avoid abuse of users we send older clients a "full-size" node, so that it's impossible for them to try and walk through a fence or wall that's created in this fashion. This was tested with a pre-bump client connected against a server running the new protocol. These nodes connect to other nodes, and you can select which ones those are by specifying node names (or group names) in the connects_to string array: connects_to = { "group:fence", "default:wood" } By default, nodes do not connect to anything, allowing you to create nodes that always have to be paired in order to connect. lua_api.txt is updated to reflect the extension to the node_box API. Example lua code needed to generate these nodes can be found here: https://gist.github.com/sofar/b381c8c192c8e53e6062

* Use LuaErrors in security check macrosShadowNinja2016-03-07
| | | | | Throwing a LuaError calls destructors as it propagates up the stack, wheres lua_error just executes a longjmp.

* Fix Lua scripting synchronizationkwolekr2015-11-01
| | | | | | | For several years now, the lua script lock has been completely broken. This commit fixes the main issue (creation of a temporary rather than scoped object), and fixes a subsequent deadlock issue caused by nested script API calls by adding support for recursive mutexes.
* Fix server crashing on Lua errorsShadowNinja2015-10-31
| | | | | | | | Previously, the server called FATAL_ERROR when a Lua error occured. This caused a (mostly useless) core dump. The server now simply throws an exception, which is caught and printed before exiting with a non-zero return value. This also fixes a number of instances where errors were logged multiple times.
* Remove some abort() callsest312015-10-26
| | | | abort() doesn't benefit from the high level abstractions from FATAL_ERROR.
* ABMs: Make catch-up behaviour optionalparamat2015-10-18
| | | | | Default is true for backwards compatibility Update lua_api.txt
* Add new ContentParamType2 "CPT2_DEGROTATE"est312015-10-04
| | | | | | | | | This might break some mods, but it is important for all uses of the param2 to be documented. This doesn't need a serialisation version or network protocol version change, as old clients will still work on new servers, and it is bearable to have new clients getting non rotated plants on old servers.
