GML Flexible Inventory System

Thank you so much everything was correct code wise i needed to add the sprite mask to the slot objects tried today have been swarmed with engineering school lately. Thank you again! now onto creating the menu.

 

Hey I am new to Gamemaker and I put the inventory in an extra room but I also want to have a hotbar if the inventory is closed. I dont know how I should do this

 

You should have the inventory as a global ds_grid, then you can reference it from anywhere in the game.
Just create some slots for the hotbar where you need them, in addition to the slots in your inventory room.

 

okay so my question is how can i take an implement this into the style of game i am making? im making an Action Role Playing Dungeon Crawler that has massive amounts of items and values!

 

This tutorial should work fine for that type of game. Nothing special you need to do to get it to work in any particular genre. The quantity of items just extends your enumerator, data structures, etcetera.

 

How would you go about making slots that only allow an Item into them based on their typing?

 

In the code where you would put items into a slot, do an additional check based on the type. There's a lot of ways you can do this, and it depends on what specific limits you want to have.
- You may have different item_gain functions that you use depending on the type, that start the for loop for finding slots at different locations.
- You could also possibly assign types, or a list of types to individual slots, either on the object or in a new data structure and check for that.

I hope that helps. It's hard to give a specific answer.

 

I appreciate the fast response. Thank you, it helps.

 

Thanks for the tutorial! I found a way to better use this with cameras/view-ports. The device_mouse_x_to_gui(device); function can be used to get the mouse x/y relative the the gui layer and you could check for the position of the mouse when you click to see if its over a inventory slot.
