| | | | Note: it does not simply add os.delete() but reverts to the "old" behavior of directly overwriting the file, because this did work before.
* Deprecate old 4590 crossingsBlockhead2020-08-21
| | | | | | | This is done with a task that runs once when the nodedb is loaded. A new field of advtrains_ndb will keep a version integer to indicate migration versions. This introduces verson 1, no version being equivalent to 0. An LBM is also registered to replace the tracks in the world.
* No longer require server priv for /at_sync_ndbGabriel Pérez-Cerezo2019-07-17
| | | | | The check for server priv was hidden where no one would have expected it.
* Various small fixesGabriel Pérez-Cerezo2019-07-16
| | | | | | - Also do atomic operations on nodedb - no longer require Worldedit for at_sync_ndb - "overrun LZB 0 restriction" should now show where it happened.

* Fix node database ATC rail bugorwell962018-10-17
| | | | | | | After successfully registering newly-placed ATC rails in the nodedb, the rail's after_place_node() callback (local apn_func()) immediately cleared it again by passing a "node" object that was actually a player object and thus had no "name" or "param2" to ndb.update(), which it handled how it should not in this situation. Since those ndb.update calls were unnecessary anyways, I removed them completely.

n class="hl com">2. Do those actions in any order: A. punch a TCB marker node to proceed route along this TCB. This will only work if this is actually a TCB bordering the current TS, and will place a route_set marker and shift to the next TS B. right-click a turnout to switch it (no impact to route programming C. punch a turnout (or some other passive component) to fix its state (toggle) for the route. A sprite telling "Route Fix" will show that fact. 3. To complete route setting, use the chat command '/at_program_route <route name>'. The last punched TCB will get a 'route end' marker The end of a route should be at another signal facing the same direction as the entrance signal, however this is not enforced and left up to the signal engineer (the programmer) The route visualization will also be used to visualize routes after they have been programmed. ]]-- -- table with objectRefs local markerent = {} minetest.register_entity("advtrains_interlocking:routemarker", { visual = "mesh", mesh = "trackplane.b3d", textures = {"at_il_route_set.png"}, collisionbox = {-1,-0.5,-1, 1,-0.4,1}, visual_size = {x=10, y=10}, on_punch = function(self) self.object:remove() end, get_staticdata = function() return "STATIC" end, on_activate = function(self, sdata) if sdata=="STATIC" then self.object:remove() end end, static_save = false, }) -- Spawn or update a route marker entity -- pos: position where this is going to be -- key: something unique to determine which entity to remove if this was set before -- img: texture local function routemarker(context, pos, key, img, yaw, itex) if not markerent[context] then markerent[context] = {} end if markerent[context][key] then markerent[context][key]:remove() end local obj = minetest.add_entity(vector.add(pos, {x=0, y=0.3, z=0}), "advtrains_interlocking:routemarker") if not obj then return end obj:set_yaw(yaw) obj:set_properties({ infotext = itex, textures = {img}, }) markerent[context][key] = obj end minetest.register_entity("advtrains_interlocking:routesprite", { visual = "sprite", textures = {"at_il_turnout_free.png"}, collisionbox = {-0.2,-0.2,-0.2, 0.2,0.2,0.2}, visual_size = {x=1, y=1}, on_punch = function(self) if self.callback then self.callback() end self.object:remove() end, get_staticdata = function() return "STATIC" end, on_activate = function(self, sdata) if sdata=="STATIC" then self.object:remove() end end, static_save = false, }) -- Spawn or update a route sprite entity -- pos: position where this is going to be -- key: something unique to determine which entity to remove if this was set before -- img: texture local function routesprite(context, pos, key, img, itex, callback) if not markerent[context] then markerent[context] = {} end if markerent[context][key] then markerent[context][key]:remove() end local obj = minetest.add_entity(vector.add(pos, {x=0, y=0, z=0}), "advtrains_interlocking:routesprite") if not obj then return end obj:set_properties({ infotext = itex, textures = {img}, }) if callback then obj:get_luaentity().callback = callback end markerent[context][key] = obj end --[[ Route definition: route = { name = <string> [n] = { next = <sigd>, -- of the next (note: next) TCB on the route locks = {<pts> = "state"} -- route locks of this route segment } terminal = <sigd>, aspect = <signal aspect>,--note, might change in future } The first item in the TCB path (namely i=0) is always the start signal of this route, so this is left out.
