Susan	065f88eec8	Feature: Allow stations under bridges. Bridges above stations will have pillars excluded if they conflict with the station layout. Based on the system implemented in JGRPP. Co-authored-by: <peter1138@openttd.org>	2025-07-28 01:18:34 +01:00
Peter Nelson	00631729a4	Codechange: Add bridge pillar exclusion information to stations and roadstops.	2025-07-28 01:18:34 +01:00
Peter Nelson	9f29f9fa56	Codechange: Add extra information to bridges about pillars.	2025-07-28 01:18:33 +01:00
Peter Nelson	adc221f0d4	Codechange: Replace station TileFlags with a TileSpec struct. This allows storing more per-layout-tile data.	2025-07-28 01:18:33 +01:00
Peter Nelson	cdadfd8e83	Codechange: Implement tile proc handler to test for building bridge over tile.	2025-07-28 01:18:32 +01:00
Peter Nelson	614a01907a	Codechange: Make functions for click and confirm beeps. (#14484 ) Avoids repetition.	2025-07-27 21:54:32 +01:00
Peter Nelson	f51067f9f5	Codechange: Give all bridge sprite tables descriptive names. (#14483 ) Finish off the work started 17 years ago...	2025-07-27 20:14:37 +01:00
