2018-01-03Connected Nodeboxes: Add `disconnected` boxesThomas--S
The `disconnected_*` boxes are the opposites of the `connect_*` ones, i.e. when a node has no suitable neighbours on the respective side, the according disconnected box is drawn. * disconnected_top * disconnected_bottom * disconnected_front * disconnected_left * disconnected_back * disconnected_right * disconnected (when there is *no* neighbour) * disconnected_sides (when there are *no* neighbours to the sides)
2017-12-11CSM fixes: load mods after flavours & add flavour to block mod loading (#6738)Loïc Blot
* CSM fixes: load mods after flavours & add flavour to block mod loading * Don't permit to load mods twice * Prepare builtin integrity global algorithm * Add missing doc & use a nicer byteflag for LOAD_CLIENT_MODS flavour * flag typo fix * Invert CSM_FL_LOOKUP_NODES & CSM_FL_LOAD_CLIENT_MODS ids
2017-12-04Zoom: Set zoom FOV per-player using a player object propertyparamat
Remove player object property 'can zoom'. Add player object property 'zoom fov'. Remove clientside setting for 'zoom fov'. Object property default is 15 degrees in creative mode, zoom disabled in survival mode. Needed due to zoom now loading and/or generating distant world according to zoom FOV. Update object properties serialisation version to 3.

2017-06-08Have the server send the player list to the client (#5924)red-001
* Have the server send the player list to the client Currently the client generates the player list based on the Client active object list, the issue with this is that we can't be sure all player active objects will be sent to the client, so this could result in players showing up when someone run `/status` but auto complete not working with their nick and CSM not being aware of the player

2017-02-10Plantlike: Fix visual_scale being applied squaredparamat
This re-applies 2 commits that were reverted. Visual_scale was applied twice to plantlike by accident sometime between 2011 and 2013, squaring the requested scale value. Visual_scale is correctly applied once in it's other uses in signlike and torchlike. Two lines of code are removed, they also had no effect for the vast majority of nodes with the default visual_scale of 1.0. The texture continues to have it's base at ground level. Send sqrt(visual_scale) to old clients. Keep compatibility with protocol < 30 clients now that visual_scale is no longer applied twice to plantlike drawtype and mods are being updated to a new value.

2017-01-01Breath cheat fix: server sideLoic Blot
Breath is now handled server side. Changing this behaviour required some modifications to core: * Ignore TOSERVER_BREATH package, marking it as obsolete * Clients doesn't send the breath to server anymore * Use PlayerSAO pointer instead of peer_id in Server::SendPlayerBreath to prevent a useless lookup (little perf gain) * drop a useless static_cast in emergePlayer

2016-08-26Make plantlike drawtype more funAuke Kok
Adds several new ways that the plantlike drawtype mesh can be changed. This requires paramtype2 = "meshoptions" to be set in the node definition. The drawtype for these nodes should be "plantlike". These modifications are all done using param2. This field is now a complex bitfield that allows some or more of the combinations to be chosen, and the mesh draw code will choose the options based as neeeded for each plantlike node. bit layout: bits 0, 1 and 2 (values 0x1 through 0x7) are for choosing the plant mesh shape: 0 - ordinary plantlike plant ("x" shaped) 1 - ordinary plant, but rotated 45 degrees ("+" shaped) 2 - a plant with 3 faces ("*" shaped) 3 - a plant with 4 faces ("#" shaped) 4 - a plant with 4 faces ("#" shaped, leaning outwards) 5 through 7 are unused and reserved for future mesh shapes. bit 3 (0x8) causes the plant to be randomly offset in the x,z plane. The plant should fall within the 1x1x1 nodebox if regularly sized. bit 4 (0x10) causes the plant mesh to grow by sqrt(2), and will cause the plant mesh to fill out 1x1x1, and appear slightly larger. Texture makers will want to make their plant texture 23x16 pixels to have the best visual fit in 1x1x1 size. bit 5 (0x20) causes each face of the plant to have a slight negative Y offset in position, descending up to 0.125 downwards into the node below. Because this is per face, this causes the plant model to be less symmetric. bit 6 (0x40) through bit 7 (0x80) are unused and reserved for future use. !(https://youtu.be/qWuI664krsI)
2016-05-28Particles: Add option to remove particles on collisionAuke Kok
Adds the particle option `collision_removal = bool` Some particles are hard to use right now since they either go through solid blocks (without collision detection), and with collision detection enabled they (e.g. raindrops) would just stop dead on the floor and sit there until they expire, or worse, scrape along a wall or ceiling. We can solve the problem by adding a boolean flag that tells the particle to be removed if it ever collides with something. This will make it easier to add rain that doesn't fall through your roof or stick on the top of it. Or clouds and smoke that don't go through trees. Particles that collide with this flag are marked expired unconditionally, causing them to be treated like normal expired particles and cleaned up normally. Documentation is adjusted accordingly. An added bonus of this patch is that particles can potentially collide many times with nodes, and this reduces the amount of collisions to 1 (max), which may end up reducing particle load on the client.
2016-03-15Add option to not send pre v25 init packetest31
The legacy init packet (pre v25) sends information about the client's password that a server could use to log in to other servers if the username and password are the same. All the other benefits of SRP of protocol v25 are missed if the legacy init packet is still sent during connection creation. This patch adds an option to not send the v25 init packet. Not sending the v25 packet means breaking compat with pre v25 servers, but as the option is not enabled by default, no servers are affected unless the user explicitly flips the switch. More than 90% of the servers on the serverlist support post v25 protocols. The patch also fixes a bug with greying out of non compliant servers being done wrongly, the min and max params were mixed.
2016-03-12Nodebox: Allow nodeboxes to "connect"Auke Kok
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
2016-01-23Backface culling: Ignore setting in tiledef from old servers.Auke Kok
Outdated servers are always sending tiledefs with culling enabled no matter what, as the value was previously entirely ignored. To compensate, we must (1) detect that we're running against an old server with a new client, and (2) disable culling for mesh, plantlike, firelike and liquid draw types no matter what the server is telling us. In order to achieve this, we need to bump the protocol version since we cannot rely on the tiledef version, and test for it being older. I've bumped the protocol version, although that should have likely happened in the actual change that introduced the new backface_culling PR #3578. Fortunately that's only 2 commits back at this point. We also explicitly test for the drawtype to assure we are not changing the culling value for other nodes, where it should remain enabled. This was tested against various pub servers, including 0.4.13 and 0.4.12. Fixes #3598
2015-09-10networkprotocol.h: remove "u16 command" from docest31
Its obvious that "u16 command" is inside every packet, therefore this commit removes all mentions of the command, if non-array like notation is used. We already didn't add "u16 command" to new packets or removed it at packet changes, so now we remove it from existing packets.
2015-07-24Bump protocol to 26est31
This was needed due to the TileDef serialisation changes. Originally it has been planned to also add utf-8 based chat to 26, but chat changes aren't final yet, so they are done in one change, after the release, and not two small ones, causing us having to be compliant to three versions of the packet.
2015-07-23Optional reconnect functionalityest31
Enable the server to request the client to reconnect. This can be done with the now extended minetest.request_shutdown([reason], [reconnect]) setting.
