World Map Location Selection Button Bugs

[cambragol]

Several issues with the WorldMap location selection buttons.

One, the top button is in a depressed state at all times. Further, when scrolling the map left or right, the top button disappears:

Further, though not necessarily related, scrolling the location selection buttons (not pressing the up and down arrows) will frequently cause the buttons to stop working. Using the up down arrow buttons restores functionality to the location selection buttons.

Part of the issue here may be a 'bug' in the background graphics for the scroll buttons.

The default graphic looks like this:

The blank area at the top is being placed behind the top entry in the location list. This means the button that is overlayed looks 'off or depressed' (slightly). Additionally, all the buttons may be disappearing, rather than just the top button, when scrolled left and right, but the lack of a background bug behind the top entry makes it appear to only happen there.

The loss of button functionality can also be triggered by clicking the up area for the scroll when the location list is at the default (top) position.

// 0x4C219C static void wmInterfaceScrollTabsStart(int delta) { for (int index = 0; index < 7; index++) { buttonDisable(wmTownMapSubButtonIds[index]); }

Does anyone know what this chunk of code is for in worldmap.cc?

commenting out the for loop fixes the above bug. But..what is the code for?

Can you post a save game so I can investigate?

Sure, but it happens with all save games. I am getting it in default Fallout 2 and Sonora, from any save (that I can see so far).
