Game Actions

Blueprint

Blueprint is a visual scripting that allows you to give behaviors to objects without using C++

It's objects that you can see in your world that you can attach behaviors too (similar to a class)

Once you have created a blueprint, you can use it throughout your project multiple times and independently.

Actor - Object that can be spawned

Pawn - Can be moved by the user

Character - Walk Around

Parent Class - Properties and functions that can be used by the child class 

Functions - Perform Tasks

Macros - Perform tasks

Variables - Store data

Event dispatchers - Perform events

Event Graph is where you add all the functionality of the blueprint

Viewport - Shows you the content of the blueprint (geometry, material, objects)

Construction Script - The default that runs at the start of the game

Components window is where you can add to your blueprint

When you make a change in blueprint, the compile button will have a yellow circle with a question mark. This means it needs to be recompiled.

When you add a mesh, there will be a marker but nothing will actually be there unless you choose what kind of mesh you want.

Adding a mesh will make it a child of the default scene root.

Once you have selected the kind of mesh, you can also add material

Actor Ticking - running code or blueprint at regular intervals

The blueprint details are where you set  the collisions and physics

Compile - runs a check to make sure there are no errors in modes

Save - Saves Changes

Brows - Opens up folder that you are working on 

Find - Look up nodes

Hide - Takes nodes out of view
