About functions

You can change the values ​​of variables simply by knowing their type and name! Simply call one of the following functions to change the variable!

1. SetFloatPropertyValueInObject

2. SetIntPropertyValueInObject

3. SetObjectPropertyValueInObject

4. SetSoftObjectPropertyValueInObject

5. SetBoolPropertyValueInObject

6. SetNamePropertyValueInObject

7. SetBytePropertyValueInObject

---

To get the value of a variable, call one of the following functions

1. GetFloatPropertyValueInObject

2. GetIntPropertyValueInObject

3. GetObjectPropertyValueInObject

4. GetSoftObjectPropertyValueInObject

5. GetBoolPropertyValueInObject

6. GetNamePropertyValueInObject

7. GetBytePropertyValueInObject

---

To create temporary storage for a variable, use one of the following functions

1. MakeFloatPropertyAttribute

2. MakeIntPropertyAttribute

3. MakeObjectPropertyAttribute

4. MakeSoftObjectPropertyAttribute

5. MakeBoolPropertyAttribute

6. MakeNamePropertyAttribute

7. MakeBytePropertyAttribute

Using attributes

Attributes are very useful when you need to initialize an object, but each object can have different parameters. As an example, we will initialize a simple Actor

1. Open any Actor and create an array of XPropertyAttribute in it.

---

2. Make this variable InstanceEditable and ExposeOnSpawn

---

3. Now on BeginPlay let's initialize our variables

---

4. Create a float variable and name it Health

---

5. Let's now display our Health on BeginPlay using PrintString

---

6. Now open LevelBlueprint and spawn our test Actor. Also, using the MakeArray and MakeFloatPropertyAttribute functions, pass the value to the Actor

---

7. Click Play and you will see that the value has been set!

---

In this way you can initialize different dynamic parameters of different Objects or Actors.

---

---

Using Attributes (Additional Example)

1. This is also very convenient when you have child classes. For example, let's create a child Actor Blueprint from our test Actor.

---

2. Open it and create a variable of type int in it and name it Count

---

3. Also, on BeginPlay after the Parent function, use PrintString to display this value.

---

4. Move these two Actors to the level

---

5. Now, we know that our Parent Actor has only a variable Health, and the Child Actor has two variables Health and Count. So select your Parent Actor in the level and in the Details panel add one element to the array XPropertyFloatAttribute

And in the Child Actor, add two elements: XPropertyFloatAttribute and XPropertyIntAttribute

---

6. Click Play and you will see that the values ​​have been set correctly.

---

---

Attributes in Data Asset

You can also use this variable type for DataAsset to store different parameters for different types of objects. This is very convenient, for example, for systems like inventory.

---

---

Additionally

You can also use Cast to determine what type of variable is used and get the values ​​manually.

PROBLEM - SOLUTION

If for some reason your attribute array is cleared after compiling the blueprint in which this variable is located, then use the XPropertyAttributes structure instead of a regular array of XPropertyAttribute objects.
