In this blueprint series, I will be going over the process on exercise 2. Let's begin. For exercise 1 I created a new blueprint class (via the content browser) and chose "Actor" for parent class. I renamed the blueprint as "BP_Variables" and opened up the blueprint. In the My Blueprint panel, I added a new variable. With the variable created, I changed the name to "BooleanVar" and Variable Type to "Boolean" and checked the Instance Editable property. I created 3 variables those being: Integer, Float and Text and named them as "Float Text or IntergerVar" of course the variable names had different names for variables. I created another Integer variable named "ArrayInteger" and set Variable Type to "Integer". I changed the variable type to "Array" and checked the Instance Editable. From there, I compiled the blueprint. Inside the Level Editor and drag and dropped the Blueprint into the level. I selected the instance of the Blueprint and editted the values of Variables in the level editor.
In Exercise 2, from the content browser I added a new blueprint class, the parent class is "Actor" and named the blueprint as as "BP_Attack". I opened the blueprint file. In Blueprint Editor. I created an integer variable named "Strength"and checked the Instance Editable. In the details panel (via Variable category), I set the value range property from "1" to "10. The default value category is set to 5. Inside the My Blueprint panel, I added a new Function and named the function as "Calculate Attack".
For the details panel I create an input parameter for Calculate Attack for Integer type and an output parameter named "Attack Value" of Integer type. Here is the following expression from the Calculate Attack value: Attack Value = (Strength x 5) + 10 I double clicked that function, editted it and created an expression (from figure 1's image in the PDF file).
