[Documentation] Touch buttons

[Meridian]

Hi everyone,

on desktops, this functionality is available via keyboard modifiers (Ctrl, Alt and Shift) and mouse buttons (RMB and MMB).

On mobile platforms, some functions are simulated via long press:
- right-click on a base facility
- right-click on a soldier in a craft to open soldier info UI
- right-click to turn a soldier and to open/close doors
- right-click to zeroize the soldier's TUs
- right-click to prime grenades in the inventory

Since OXCE v7.0, many other battlescape functions are also available via on-screen touch buttons.
The touch buttons can be activated via extended links, see: https://openxcom.org/forum/index.php/topic,9506.0.html

The buttons can be used for the following functionality:
- shift: ignore spotted enemies/mutual surprise
- ctrl: running
- ctrl: strafing
- ctrl: force-fire
- ctrl+shift: spray targeting
- alt: cursor damage preview
- alt: motion scanner arrows
- alt: unit facing preview
- alt: temporarily turn off camera following projectiles
- alt: minimap borders preview
- RMB: unit turning
- RMB: door opening
- RMB: next unit icon click = select previous unit
- RMB: weapon click = reaction fire preference (yellow dot)
- ctrl+RMB: tank turret turning
- MMB: unit/alien inventory preview
- MMB: weapon/special weapon click = Ufopedia

Big thanks to robin to the button artwork.

I notice there are some artifacts on the TFTD buttons. Is there something that I need to fix?

Edit: could be related to the palette? I noticed the "pure white" color appears 3 times, one of which is in the transparent position (the last color).
Strange. I used the top one (see attachment), but the circled ones are all the same color.
I'm not really familiar with this palette, I used the depth-0 one, but I used the standard colors used in the default UI, those should be always there.

Yeah, the palette seems to have white color on index 255 in your image.

The color in the game is close to pure black though. e.g. rgb (0,20,16)  #001410 in hex

Btw. index 255 is not transparent, only index 0 is transparent.

You can use the palette from `oxceLinks.png` in `\standard\xcom2\Resources\Extended\` if you want.

seems an issue with photoshop, if I extract the palette from a tftd sprite sheet, I still get the white color in the last index...
no wait, even using irfanview on PCK-viewer extracted images, shows white. lol

I prepared photoshop palettes here: https://github.com/MeridianOXC/OpenXcom/tree/oxce-plus/bin/common/Palettes/TFTD-ACT-SAFE

If you download from there, does it look better?

I'm not exactly sure which one is mostly used to draw battlescape sprites, I think it's either PAL_BATTLESCAPE_2_SAFE.act (or PAL_BATTLESCAPE_SAFE.act).

[robin]

This should be fixed.
My old version of photoshop is a pain in the ass for managing the palettes.

I think you should upload link those palettes here:
https://openxcom.org/forum/index.php/topic,1557.0.html
the ones already there are problematic at this point.
Edit: nope, my photoshop can't into your palettes, I have to fix manually my old ones. Anyway the attached buttons should be ok, hopefully.

thank you

[robin]

no problem!
let me know if you notice something else.

At last! Many thanks.
