allow mods to pass a function or just true

to the pole and horiz pole check routines, in case they need their own, custom checking routines, if the usual, simple checks aren't good enough. got rid of the allowed-poles table, as it's now obsolete moved all existing special code into compat.lua, altered to use this feature.
fix empty lines being skipped

Author	SHA1	Message	Date
Vanessa Dannenberg	dcdee22265	allow mods to pass a function or just `true` to the pole and horiz pole check routines, in case they need their own, custom checking routines, if the usual, simple checks aren't good enough. got rid of the allowed-poles table, as it's now obsolete moved all existing special code into compat.lua, altered to use this feature.	2019-09-22 03:19:31 -04:00
Vanessa Dannenberg	e4336e320c	fix empty lines being skipped	2019-09-21 22:04:39 -04:00
Vanessa Dannenberg	d41e2ffd73	use a meta key to select wide-font mode instead of using a separate node add LBM to convert old nodes.	2019-09-21 21:42:46 -04:00
Vanessa Dannenberg	77987d12b9	detect streets:bigpole_tjunction Treat T-junction as a vertical or horizontal pole (depending on its orientation), if the sign could be placed flat against the back or side of the junction. In this instance, the "front" of the junction is the side with the middle bit sticking out, and will just get a regular wall signif targeted, as with any non-pole node.	2019-09-21 21:39:53 -04:00
Vanessa Dannenberg	dfece5275e	rework horizontal pole detection slightly	2019-09-21 19:24:48 -04:00
Vanessa Dannenberg	6285d250d7	default "allow_onpole" to disabled for consistency with other similar flags	2019-09-21 15:56:45 -04:00
Vanessa Dannenberg	9502812088	Add necessary bits to allow signs to be placed onto horizontal poles (both wooden and steel signs) only streets mod's "bigpole" supported for now. Model changes: To make a sign support horizontal mounting, make a single "_onpole" model, with two copies of the pole mount, one rotated by 90°. Make sure the second copy appears has its own material entry, and that it is last in the materials list in the exported .obj (`grep "g " file.obj` to check). When registered, signs_lib will set the "_onpole" and "_onpole_horiz" tiles{} to reveal one mount or the other: entry 3 will expose the vertical mount, entry 4 is the horizontal copy, with the opposite entry being set to the "blank" image.	2019-09-21 15:45:48 -04:00
Vanessa Dannenberg	c66c1b70bd	disable backface culling on the sign entity (allows for transparent signs i.e. glass)	2019-09-19 01:02:44 -04:00
