Unreal Engine 4 UI Grid Slots

posted by: Vinícius Cordeiro Feb 8, 2020

Creating dynamic inventory with Unreal Engine, is easy you just need to know where to start so I will help you with some tips
→ Use C++ as calculations can be faster and dynamically changed using integration with blueprints
→ Use singletons and interfaces to store informations globally so can acessed easier
→ Always comment your comments with the necessary informations you may need after you need later to maintain the code working

First off create a new C++ project if you don't already have one, after that import any kind of interface stuff you want to your items for now i will not import anything
I will use the basic borders and images from unreal engine,

Now create a new C++ class of type UUserWidget with the name of _slot, use public (the reason of using the _ before the name is to avoid conflicts with engine default slot names) this will give you access to the user widget class inheritence from the engine defaults. after the code compiles and Visual studio is opened fix some errors that may happen if some sort of weird bug happen. Usually is the include file on the source file that is not with the correct path just fix it

                                // Your copyright notice
                                #include "Public/YourFilePath/_slot.h "
                            

_slot.cpp

                                // Your copyright notice
                                #include "Public/YourFilePath/_slot.h"
    
                            // Initialize all the neccessary slots and informations inside the slot as images and borders
                            bool _slot::Initialize()
                            {
                                Super::Initialize();
                                // we need a valid background image and a valid icon image object otherwise this cannont be initialized
                                if(!_background || !_icon) return false;
    
                                // set the color of this background and make the icon transparent/invisible
                                _background->SetColorAndOpacity(FLinearColor(0.5f,0.5f,0.5f,0.5f));
                                _icon->SetColorAndOpacity(FLinearColor(0.f,0.f,0.f,0.f));
                            }
                            

Back to the engine create a new C++ class of the type UUserWidget with the name of _grid do the same thing fixing the same issues from the bug, notice that this may or may not happen to you

                                //Your Copyright Notice
                                #include "Public/YourFilePath/_grid.h "
                            

With this problem fixed we can procced to the next steps to create our grid slot "inventory " panel
