Medals Limit Oddity
Although it is true that one can have more medals in current FSO builds than with retail, there is one oddity which I haven't seen documented.

FSO uses color indexed mask files in its interface.  In the case of the medals screen, the mask uses colors starting from rgb 255/255/255 used for the first medal appearing in medals.tbl, with the color index decrementing by one for each additional medal.  However, FSO reserves the RGB color index 237/237/237 for the close screen button (a fact undocumented anywhere I could find).  If one wants to create more medals than exist in retail, one therefore needs to create a placeholder "medal" entry in medals.tbl in the right place so that no actual medal is assigned to color 237, as in this snippet.

Code: [Select]
; #3
$Name:          Flight Training
+Position 1024: 563,256
+Debriefing Bitmap:
$Num mods:      1

; phony medal here to stand in for the close button
; the close button is hard coded to occupy this slot
$Name:          Exit Button
+Position 640: 463,256
+Position 1024: 914,659
+Debriefing Bitmap:
$Num mods:      1

; #2
$Name:          Combat Action Medal
+Position 640: 463,256
+Position 1024: 463,256
+Debriefing Bitmap:
$Num mods:      1

Is this actually the intended behavior of the medals table?  One would think that FSO would use the color index (255-Total number of medals-1) for the close button and not a hard coded value.  At the very least the medals.tbl wiki should be updated with this information (which I am happy to do).

If a man consults whether he is to fight, when he has the power in his own hands, it is certain that his opinion is against fighting.

Re: Medals Limit Oddity
Well that's certainly interesting. Honestly, I think an easier solution would be to allow us to specify the color index in the medals.tbl for each medal. If not there, default to retail behavior.

Re: Medals Limit Oddity
To be pedantic, the hotspot index isn't the RGB color index, but rather the index in the PCX 256-color palette.  It just so happens that these are almost always the same.  (The reason I discovered this is that I ran across a mask file that didn't follow that convention.)

But I found it; the offset is indeed hardcoded:

Code: [Select]
#define MEDALS_EXIT 0
ui_button_info Medals_buttons[GR_NUM_RESOLUTIONS][MEDALS_NUM_BUTTONS] = {
{ // GR_640
ui_button_info("MEB_18", 574, 432, -1, -1, 18),
{ // GR_1024
ui_button_info("2_MEB_18", 919, 691, -1, -1, 18),

That number 18 is the hotspot: 255 - 18 = 237.

It shouldn't be too hard to add a feature that allows you to specify the close button's index in medals.tbl.
