Vanessa Dannenberg	ea4151dfa7	Use 9-slicing to build inventory-type backgrounds This way the slots are all nice and crisp regardless of GUI scale or image size, and we only need the single slot and its bright version. This also makes the standard crafting grid into a style table entry that can be referenced to insert the crafting grid at its proper style-specific position in any formspec. And it also makes the craft grid arrow, its X position, and the crafting grid's result slot X position into style table entries. Includes a few public helper functions to do most of the work: `ui.single_slot(xpos, ypos, bright)` Does just what it sounds like: it returns a single slot image. `xpos` and `ypos` are normal coordinates in slots, as you'd use in `image[]` element. `bright` is a flag that switches to the brighter version of the slot image. `ui.make_trash_slot(xpos, ypos)` Creates a single slot, with a one-item `list[]` and a trash can icon overlay. `ui.make_inv_img_grid(xpos, ypos, width, height, bright)` Generates a `width` by `height` grid of slot images, using the single_slot function above, starting at (`xpos`,`ypos`) for the top-left. Position is as in any `image[]` element, and dimensions are in integer numbers of slots (so 8,4 would be a standard inventory). `bright` is as above. All three return a string that can be directly inserted into a formspec.	2021-03-08 12:32:13 -05:00
Vanessa Dannenberg	d063af1d27	Draw the trash slot by overlaying the bare trash can icon over the single slot image instead of baking it in.	2021-03-08 09:53:25 -05:00
Vanessa Dannenberg	250d038d0b	don't display the refill slot image if no creative priv/mode (leftover from when it was part of the craft grid image) Also fixed a typo in the corresponding list[] element that made it not work.	2021-03-08 09:14:21 -05:00

Vanessa Dannenberg	51de368949	using a table.copy() to pass the style tables around requires setting-up items_per_page, standard_inv, and standard_inv_bg for both tables at init time.	2021-03-08 05:10:16 -05:00
Vanessa Dannenberg	e61ae0e149	always modify and return a table.copy() of the style table	2021-03-08 05:10:00 -05:00
Vanessa Dannenberg	531442c63e	move S() calls into waypoints' button table instead of inside the loop	2021-03-08 05:10:00 -05:00
Vanessa Dannenberg	62881d9938	Multiple related changes to string handling 1) Convert most formspec elements to use string.format(), when the result would be more readable, or less messy, or at least makes the line shorter, assuming it looked like it really needed it to begin with. 2) Convert all long `foo..","..bar..";"..baz..bleh..` types of excessive string concatenation into tables that then get concated only once, when their containing functions return the final formspec string. 3) In some places in the code, such tables were already being used, and were named "formspec", while others were named "fs". I settled on just one name, "formspec", as it's more readable, if longer. 4) There was a mix of styles of adding items to those tables: * Some places used line after line of `t[#t + 1] = foo/bar/baz`. * Others places used the form `t[1] = foo, t[2] = bar, ...`. * Still others used the form `t[n] = foo, t[n+1] = bar...`, with `n` being increased or reset every so often. Most of them should now be of the third form, with a few of the second.	2021-03-08 05:10:00 -05:00
Vanessa Dannenberg	55692900f9	use local "ui" to reference "unified_inventory", where practical (makes code shorter, easier to read and write)	2021-03-08 05:10:00 -05:00

Vanessa Dannenberg	a5a09bcd3a	bump minimum version to 5.4.0	2021-03-06 13:35:34 -05:00
Vanessa Dannenberg	e8e1d4d705	Convert over to formspec version 4 I recreated the original layout as best as practical, but by necessity there are a few minor positioning changes, since the underlying hard-wired inventory slots are square now and image positioning is now scaled by exactly 1.250 in both dimensions (as opposed to roughly 1.25 by 1.16). Backstage, I also needed to fix the aspect ratios of the various inventory slot elements. That meant redesigning the single-slot image from scratch. It was already blurry/grainy and a little ugly, and trying to alter it would have only made it worse. The slot image is now exactly 56x56 pixels square, set on a 64x64 canvas, so there's a 4 pixel empty space around the edges. The full 256px .xcf workfile is included in the UI folder. I've re-tiled all slot/inv images from the new single slot. I also re-rendered the trash can icon from it since it was blurry and oddly-sized. I couldn't find the original upstream image, so since they're free, I used one of my Linux system's icons which happens to resemble it. I also removed a couple more improper uses of `background[]` where `image[]` is more appropriate. There are tons of minor tweaks throughout the code to re-align everything, and I had to rewrite a few sections to avoid code duplication and to allow for a little more flexibility (mainly to make "lite" mode look right).	2021-03-06 13:22:20 -05:00
