Generally that means that you haven't scripted anything for that button... Check to make sure that the button you are clicking is the button# you used in interface_click(int button)... And try posting the script as well...

And that is only part of it. Since I can't exceed the 20000 characters limit in these forums. I am forced to double post and here is the rest of it:

You forget to add one essential line into interface_click:

function interface_click(int interface, int button) {

// calling our function for clicks over sldGUI:
if (interface == sldGUI) interface_click_SaveLoadDialogGUI(button);

...
...

Edwin Xie · « **Reply #44 on:** 23 Oct 2004, 20:43 »

Thanks. Uhoh, now I realized that when I read your post it took almost 100 seconds. With 19 queries. Maybe I was downloading that game at 10kbps when it should normally be about 4kbps.

Edwin Xie · « **Reply #45 on:** 23 Oct 2004, 22:44 »

I have one final question to ask, which lines do I have to modify to make it so that the player can save a limit of 100 save game slots?

Scorpiorus · « **Reply #46 on:** 24 Oct 2004, 00:27 »

It's not currently possible to rise the limit beyond 20. As I said before, I'll look into how it can be increased and reply back then.

monkey_05_06 · « **Reply #47 on:** 27 Oct 2004, 01:26 »

It is currently possible, just not using the savegameindex[] array...

You have to use SaveGameSlot(int slot, string description) and RestoreGameSlot(int slot). However, this changes the way you have to set up your listbox. You could use something like:

[code]function ListBox(int gui, int object){
string buffer, description;
int counter;
ListBoxClear(gui, object);
while (counter<100){
StrFormat(buffer, "%d. ", counter+1);
if (GetSaveSlotDescription(counter+100, description)!=1) StrCopy(description, "");
StrCat(buffer, description);
ListBoxAdd(gui, object, buffer);
counter++;
}
ListBoxSetTopItem(gui, object, 0);
ListBoxSetSelected(gui, object, -1);
}[/code]

Thanks to Proskrito for the script... I don't know if you wanted your listbox items numbered, but if not, you can just do:

[code]function ListBox(int gui, int object){
string description;
int saveslot;
ListBoxClear(gui, object);
while (saveslot<100){
if (GetSaveSlotDescription(saveslot+100, description)!=1) StrCopy(description, "");
ListBoxAdd(gui, object, description);
saveslot++;
}
ListBoxSetTopItem(gui, object, 0);
ListBoxSetSelected(gui, object, -1);
}[/code]

Or something like that...

A minor plug - version 1.1 of my Black Cauldron remake contains a custom save/restore dialog box with support for more than 20 slots. In retrospect I could have optimised it further, since I didn't know about the GetSaveSlotDescription method, but you may get some good ideas for it. Basically, I use a custom file to store the current ordering of save game slots, and then use it to load the listbox with the save games in the correct order.
