DKoepp's Item Editor

Yes. No hex editing is required.
After undatting the various .dat files, go into the rules folder. You will find SpellList.mes which defines all the spells.
Then simply change the duration of the potion of haste and save the file in the data\rules directory.

// 6 -- mtMI2PotionHaste [Item: Potion of Haste]
{13600}{AoE: Tgt_None, [Begin]AoE: Tgt_Obj_T_Critter | Tgt_Obj_No_ST_Critter_Dead, [End]AoE: Tgt_Object}
{13601}{Cost: 0, Duration: (60 @ -1), Range: 2, Info: friendly}
{13603}{No_Stack: 1, ItemTriggers: Item_Used}
{13604}{AI_Defensive: (3 @ 0)}
{13605}{[Begin], ItemTriggers: Item_Used, Type: Effect, 332, Add, Count: 8, Scaled: 16} // +20 Speed
{13606}{[Begin], ItemTriggers: Item_Used, Type: EyeCandy, 2, Add}
{13607}{[Begin], ItemTriggers: Item_Used, Type: EyeCandy, 3, Add, Play: Stack}
{13608}{[End], ItemTriggers: Item_Used, Type: Effect, 332, Remove, Count: 8, Scaled: 16}
{13609}{[End], ItemTriggers: Item_Used, Type: EyeCandy, 2, Remove}
{13610}{[End], ItemTriggers: Item_Used, Type: EyeCandy, 3, Remove}
{13611}{[End], ItemTriggers: Item_Used, Type: EyeCandy, 2, Add, Play: Reverse} // Dissipating

This is the relevant line for changing duration of the spell:
{13601}{Cost: 0, Duration: (60 @ -1), Range: 2, Info: friendly}

At the moment I have no desire to learn java so don't look at me. However recently I discovered how to comprehensively edit critters using nothing more than a text file. At some point I will write up the details of how to do it. But in the meantime the short version:
In the rules folder you will find 3 text files: Unique, NPC and Monster. Changing the text within these files will update the protos used by the game. However NPC seems quite resistant to change for some unknown reason. Also, do NOT alter or add internal names. Madness this way lies.

 

{13603}{No_Stack: 1, ItemTriggers: Item_Used}

By changing the No_Stack: part of this line could you make potions and such stackable?

 

No joy.

 

If you mean stack as in stack in inventory then the answer is no.
Stack in this case means the effect stacks. So if stack is set to 0 then you can have has many of that item in effect at any one time as you wish. If stack is set to 1 then you can only have a single instance of this item active at any one time.

 

I just got a crazy idea for potions of haste...

 

If you're thinkin' what I think you're thinkin'..... :lol:

 

instead of the 60 (as given in the example) do I just need to enter a huge number? or is 0 the infinity number ?

 

So putting the stack at 0 and the duration time at 0 then I would have made an potion than never disapears after use with an never ending effect right ?

 

You can stack as many as you want, and the effect never fades. It'd be like spiking a red bull with some crack.

 

Some question, I didn't manage to get these alterings to work. Do I need a game where my character didn't have the object yet?

I know edited maps only work when you didn't visited before.

I still don't quite understand what that stacking part does. Is it like gold and arrows that 1 icon has more of the same sort? I thought it would be the number of times it could be used until the item disapears...As my modifications do not work, I still can't test it.

Sorry for getting way offtopic...

 

ohhhhhhh

now I get it, Thanks.
