Is there any easy way to keep buttons inside of box? (c#)

Question

I made an inventory script, but I would love for it to auto-determine how many buttons can fit in a row, and put them on the next row. Is there any way?

Edit: even not "auto determining" but if I say that 2 buttons fit on each row, I would like it to auto-move the next set to the next row and PREFERABLY resize them.

Here is the important part of my current script:

         GUI.BeginGroup (new Rect(Screen.width/2 +100, Screen.height - 300, 400, 100));
         GUI.Box (new Rect(0,0,400,100), "Weapons");
         foreach(GameObject inv in inventory)
             {
             if(invcount < inventory.Count)
                 {
                     invcount ++;
                 }
             if(GUI.Button (new Rect(10 + (invcount - 1) * 205,20,200,30),new GUIContent(inv.name, "Damage: " + inventory[invcount-1].GetComponent<Item>().dmg)))
                 {
                     Debug.Log ("equipping" + inv.name);
                                 if(hasCloned)
                 {
                     Destroy (clone1);
                 }
                 toUpdate = true;
                 hasCloned = true;
                 if (toUpdate)
                     {
                      
                         clone1 = Instantiate(inv, WepHolder.transform.position, WepHolder.transform.rotation) as GameObject;
                         clone1.transform.parent = GameObject.Find ("Main Camera").transform;
                         clone1.SetActive (true);
                         Debug.Log ("You are now using: " + inv.name);
                         clone1.tag = "weaponEquipped";
                         toUpdate = false;
                     }
                 }
             GUI.Label (new Rect(10 + (invcount - 1) * 205, 70, 100, 30), GUI.tooltip);
 
             GUI.tooltip = null;
             }

You could draw your buttons in a loop and then after [size of row] objects, change the y value.

If you were using GUILayout, it'd be somet$$anonymous$$ng like t$$anonymous$$s:

 int size = inventory.Count
 int rowLen = 5;
 GUILayout.BeginVertical();
 GUILayout.BeginHorizontal();
 for(int i=0; i<size; i++){
     GUILayout.Button( content);
     if( (i+1)%rowLen == 0){ //if the next object needs to be on a new row
         GUILayout.EndHorizontal(); //end row
         GUILayout.BeginHorizontal(); //create new row
     }
 }
 
 GUILayout.EndHorizontal();
 GUILayout.EndVeritcal();

If you're not using GUILayout, you'll have to do somet$$anonymous$$ng a little more fancy like t$$anonymous$$s:

 int xPos =  10 ; //xpos of first button
 int yPos = 10;  //ypos of first row;
 int xSpacing = 5; //horiz distance between buttons
 int ySpacing = 5; //vert distance between buttons
 
 int buttonW = 50;
 int buttonH = 10;
 
 int size = inventory.Count;
 int rowLen = 5; //number of items per row
 
 int currX = xPos;
 int currY = yPos;
 
 for(int i=0; i<size; i++){
     GUI.Button(new Rect(currX, currY, buttonW, buttonH);
     currX += xSpacing;
     if( (i+1)%rowLen == 0 ) 
        currY += ySpacing;
 }

Slight Caveat Don't copy t$$anonymous$$s code verbatim. No clue if it actually works or is the correct syntax, but should be pretty close. I wrote t$$anonymous$$s off the top of my head without Unity around
