From 9b0ec771d70c4bdc97a08f480a1a9c31b1ee8ca1 Mon Sep 17 00:00:00 2001 From: orwell96 Date: Tue, 29 Jun 2021 16:12:29 +0200 Subject: Train-World collisions: Collide only with 'normal'-drawtype nodes. 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. --- advtrains/trainlogic.lua | 43 ++++++++----------------------------------- 1 file changed, 8 insertions(+), 35 deletions(-) diff --git a/advtrains/trainlogic.lua b/advtrains/trainlogic.lua index 0fb778b..7093929 100644 --- a/advtrains/trainlogic.lua +++ b/advtrains/trainlogic.lua @@ -1369,43 +1369,16 @@ end --not blocking trains group function advtrains.train_collides(node) - if node and minetest.registered_nodes[node.name] and minetest.registered_nodes[node.name].walkable then - if not minetest.registered_nodes[node.name].groups.not_blocking_trains then + if node and minetest.registered_nodes[node.name] then + local ndef = minetest.registered_nodes[node.name] + -- if the node is drawtype normal (that is a full cube) then it does collide + if ndef.drawtype == "normal" then + -- except if it is not_blocking_trains + if ndef.groups.not_blocking_trains and ndef.groups.not_blocking_trains ~= 0 then + return false + end return true end end return false end - -local nonblocknodes={ - "default:fence_wood", - "default:fence_acacia_wood", - "default:fence_aspen_wood", - "default:fence_pine_wood", - "default:fence_junglewood", - "default:torch", - "bones:bones", - - "default:sign_wall", - "signs:sign_wall", - "signs:sign_wall_blue", - "signs:sign_wall_brown", - "signs:sign_wall_orange", - "signs:sign_wall_green", - "signs:sign_yard", - "signs:sign_wall_white_black", - "signs:sign_wall_red", - "signs:sign_wall_white_red", - "signs:sign_wall_yellow", - "signs:sign_post", - "signs:sign_hanging", - - -} -minetest.after(0, function() - for _,name in ipairs(nonblocknodes) do - if minetest.registered_nodes[name] then - minetest.registered_nodes[name].groups.not_blocking_trains=1 - end - end -end) -- cgit v1.2.3
