Inventory increase

Crow · October 6, 2023

Dear Devs,

Since I couldn't find a topic like this, I thought I'd open one. My problem is that I just can't figure out where I can increase max inventory towards 256.

Images:

In the first picture, the first 4 inventories look like this, but the 5th can only hold 4 blessing scrolls. 4x63=252+4=256

So I would have to rewrite BYTE, but it just doesn't work out anyway.

I'll share a few lines of code that I've rewritten in case I need something else that I don't know about at the moment.

exchange.cpp:

bool CExchange::CheckSpace()
{
	static CGrid s_grid1(5, INVENTORY_MAX_NUM/5/6);
	static CGrid s_grid2(5, INVENTORY_MAX_NUM/5/6);
	static CGrid s_grid3(5, INVENTORY_MAX_NUM/5/6);
	static CGrid s_grid4(5, INVENTORY_MAX_NUM/5/6);
	static CGrid s_grid5(5, INVENTORY_MAX_NUM/5/6);
	static CGrid s_grid6(5, INVENTORY_MAX_NUM/5/6);
	
	s_grid1.Clear();
	s_grid2.Clear();
	s_grid3.Clear();
	s_grid4.Clear();
	s_grid5.Clear();
	s_grid6.Clear();

	LPCHARACTER	victim = GetCompany()->GetOwner();
	LPITEM item;

	int i;

	const int perPageSlotCount = INVENTORY_MAX_NUM / 6;

	for (i = 0; i < INVENTORY_MAX_NUM; ++i) {
		if (!(item = victim->GetInventoryItem(i)))
			continue;

		int32_t itemSize = item->GetSize();

		if (i < perPageSlotCount)
			s_grid1.Put(i, 1, itemSize);
		else if (i < perPageSlotCount * 2)
			s_grid2.Put(i - perPageSlotCount, 1, itemSize);
		else if (i < perPageSlotCount * 3)
			s_grid3.Put(i - perPageSlotCount * 2, 1, itemSize);
		else if (i < perPageSlotCount * 4)
			s_grid4.Put(i - perPageSlotCount * 3, 1, itemSize);
		else if (i < perPageSlotCount * 5)
			s_grid5.Put(i - perPageSlotCount * 4, 1, itemSize);
		else
			s_grid6.Put(i - perPageSlotCount * 5, 1, itemSize);
	}

Hope someone can help.

I have no idea what I'm missing out.

Thank you in advance for your answers.
