Hi, I didn’t figure out how to write a good title, sorry.

I’m trying to make a grid of buttons to appear as an inventory. I’m totally new at Unity, please excuse my ignorance…

I’m rendering the inventory on the OnGUI event, I specify the position and size of the inventory area, and then I specify a portion of it to an area called tooltipArea. I want to hover a button and a tooltip that appears on the bottom part of the inventory (in the tooltipArea), with some characteristics of the item hovered.

What I did is that I assigned the tooltip to a button succesfully, but this tooltip won’t appear if it’s outside of the button area.

This is a screenshot of what I have:

Inventory

And this is my code:

void OnGUI(){
		GUI.skin = inventorySkin;		
		if(isMenuOpen){
//These boxes are for seeing what space are this areas actually occupying
			GUI.Box(new Rect(inventoryAreaNormalized.x - inventoryBackPadding, inventoryAreaNormalized.y - inventoryBackPadding, inventoryAreaNormalized.width + inventoryBackPadding*2, inventoryAreaNormalized.height + inventoryBackPadding),"");
			GUI.Box(new Rect(tooltipArea),"");
			GUI.BeginGroup(inventoryAreaNormalized);			
			int count = 0;

//My intent of grid...
		
			for(int renglon = 0; renglon < nrenglones; renglon++){
				var top = renglon * baseItemArea.height;
				for(int columna = 0; columna < colSize ; columna++){
					var left = columna * baseItemArea.width;
					var thisRect = new Rect(left, top, baseItemArea.width, baseItemArea.height);	
					
					if(Inventory.ItemBag.Count > count){						
						if(GUI.Button(new Rect(thisRect), new GUIContent(Inventory.ItemBag[count].Quantity.ToString(), Inventory.ItemBag[count].Icon, Inventory.ItemBag[count].Name))){							
							//Some actions
						}

						//THIS DOES NOT WORK
						if (!string.IsNullOrEmpty(GUI.tooltip))   
							GUI.Box (new Rect(tooltipArea), GUI.tooltip);
						
						count++;
					}else if(renglon * colSize + columna + 1 <= Inventory.Capacity){ 
						if(GUI.Button(new Rect(thisRect), "")){	}											
					}else{  items
						GUI.Box(new Rect(thisRect),"");
					}
				}				
			}		
		GUI.EndGroup();
		}
	}

Ok, so please, any guidance is very welcome, I’m just playing around and I can’t figure this out, I searched in the questions in this forum and I didn’t got this particular question.

Again, to clarify, this line:

GUI.Box (new Rect(tooltipArea), GUI.tooltip);

only works like this

GUI.Box (new Rect(thisRect), GUI.tooltip);

placing the tooltip over the button (an undesired effect).

Edit:

So I changed

GUI.Box (
    new Rect(thisRect.x+15,
            thisRect.y+15,
            thisRect.width,
            thisRect.height), GUI.tooltip);

just to see if it had something to do with the button area, but no. This is the result:

Edit

Why is the tooltip ignoring the tooltipArea? What am I missing?

Can’t believe my ignorance and inexperience.

Never ocurred to me that this bit was the thing I was not aware of. Sorry all.

GUI.BeginGroup(inventoryAreaNormalized);

Everything inside it is a ‘child’ of it, and I forgot.
