* Address wagon aliasing issuesY. Wang2024-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As it turns out, not fully testing new features is not necessarily a good idea ... This patch follows up 1F616EMO's patch by * Making get_wagon_prototype return the resolved alias, * Handling recursive wagon alises (in particular, loops), and * Adding (partial) unittest for the wagon aliasing system. [v2]: The testcases are complemented a bit more to cover situations where the alias resolution system should return nil. [v2]: This patch should hopefully also warn about not spawning wagons. Note that this only warns about the missing wagon entity and does _not_ actually fix the issue. How to test: * In a world with both advtrains_train_subway and advtrains_train_japan enabled, place a subway wagon, a Japanese engine, and a regular Japanese wagon. * Add the test mod to the world; do NOT remove advtrains_train_japan. * Restart the world. Notice that the Japanese wagons still appear as Japanese wagons despite being aliased to subway wagons. * Restart the world without the advtrains_train_japan mod. Notice that the engine appears as the subway wagon while the regular Japanese wagon appears as the wagon placeholder. [v2]: Also note that the warning message about the missing wagon prototype still mentions the regular Japanese wagon. * Restart the world again with the advtrains_train_japan mod. Notice that both type of Japanese wagons reappear as Japanese wagons. * Observe that unittests work. Test mod: advtrains.register_wagon_alias("advtrains:engine_japan", "advtrains:subway_wagon") advtrains.register_wagon_alias("advtrains:wagon_japan", "advtrains:wagon_japan")

* On-Track Collision system: Fix train teleportation when using ↵orwell962021-11-04
| | | | | | split_at_index() from LuaATC Issue was that train thought it would collide with the newly added back portion although it was already long past this train. Added additional check that current train index is not further than the collision point.
* Train Coupling: Change behavior so that train direction of initiating train ↵orwell962021-10-25

* Rework train same-track collision system and deterministic couplingorwell962021-07-07
| | | | | | | - Adds a separate collision system for trains sharing a path - Moved some coupling-related code to couple.lua and refactor it - Handle coupling in a way that the initiating train always keeps its ID - As a side effect, engine has its direction reversed after coupling
* Make the collision mode configurableGabriel Pérez-Cerezo2021-06-30
| | | | | | | | If the advtrains_forgiving_collision setting is set to true, then the train only collides with nodes that do not have normal drawtype. Otherwise the old behavior is restored. This change is being made because there were users and mods relying on the old behavior, such as the railroad_paraphernalia mod's track blocker.
* Train-World collisions: Collide only with 'normal'-drawtype nodes.orwell962021-06-29
| | | | | | | As per discussion on the forum (https://forum.minetest.net/viewtopic.php?p=396745#p396745), changes the train-world collision logic to make trains only collide with nodes that are solid cubes. This allows for more creative freedom, but shifts the responsibility of building realistic railways to the players. In the future, a more sophisticated environment collision system might be invented, but this is low-priority and should be optional to save CPU.
