How to change a button in character menu by a custom script call

[Phrono 0]

Hi, everybody:

 

This was originally a question for Lizzie, related with his Mission/Quest Menu script, (http://www.gdunlimited.net/scripts/rpg-maker-xp/window-scripts/mission-quest-menu-script) but as I have noticed that he had been a long time without logging in, I'd rather ask here and see if anyone can help:

I've been trying to implement that script for quests in my game, but I have not managed to replace the "save" button in the main menu by calling the missions menu. 

In my game the save option is disabled by default, so I'd like to replace that one button to call the mission menu. 

I already have the names of the missions, have the script working properly, all lines that explain missions, etc perfectly functional, and I have been several days tinkering with scripts (especially Scene_Menu) but can not get it to work. 

Would you be so kind as to tell me where I have to replace the call to "$scene=Scene_MissionMenu.new"?

It's probably something super-simple, but I'm not very handy with scripts (I've little time using them, and don't understand the syntax properly) and although I've searched the forums, can't find nothing to help me... most of the explanations that I find on changing menus are not designed to custom function calls.  :ehh: 

I hope somebody can help me... Thank you very much!

If you want to replace the Save button, you would need to go to Scene_Menu and search "$scene = Scene_Save.new" and replace it with "$scene=Scene_MissionMenu.new". That would change the command of the button.

I did what you told me and sure enough, the button appears, but does not let me access the quest menu, (it plays the "disabled" sound) but I made sure that the call to mission is made and the corresponding id enabled

Probably the lines for when Save is disabled is still there. If you remove that, I reckon it should work.
