What are you learning?

Unreal Engine - Last individual project

Why is it important?

Show what you can do

How do you show that you understand? What is the assignment?

You have created a parkour course and a maze.

This week, you are to combine those skills to create a puzzle game with pressure plates.

Your game must have a minimum of 10 parkour elements so a player must jump and land somewhere to continue the game

You game must have at least 10 dead ends

Your game must include the use of five pressure plates in order to continue the game

You game must take a minimum of three minutes to play from start to finish.

Once you have completed your game, you are to record the game play using screenpal (formerly screencastomatic) or a similar screen recording software to record you playing your game from start to finish. You are to explain what you chose to use and why while you are playing through your game.

If you finish early, you are to continue to add assets to your game.

Points

10 Parkour Elements - 2 Point

10 Dead Ends - 2 Point

5 pressure Plates  - 2 Point

Three Minutes of game play - 2 Point

Video with explanation - 2 Point

Total 10 Points

**Adding Physics to Objects**

Window

Place Actor

Choose one and add it to your game

Make sure simulate physics is selected in details panel

You can check the Mass Box in your details to change the weight

Exporting Blender Files

Name It

Operator Presets - Default

Select Objects

Geometry

-Smoothing Face

Unclick bake animation

Open your content drawer and open the blueprints folder then open the FirstPersonTemplate Folder

Right Click

Find Blueprints

Select Blueprint Interface

Name it BPI_Interaction and double click to open it up

In the functions in the right side, create a function called Interact

Compile and save

Go back to your First person map

Open your content drawer and the doors folder in your blueprints

Right Click on the Door Parent Blueprint and select Create Child Blueprint Class

Name it PBC_Door_Interface

Double Click to open it up

We are going to add the interface to the actor by clicking Class settings at the top

Under Interfaces in the Details Panel

Click ADD

search for BPI_Interaction

Once you have added it, you should see it in the Interfaces in the MyBlueprints Tab on the left

Right Click on the Interact and select Implement Event

This will open up your Event Graph

From your Event Interact Node, pull out a Flip Flop from the Exec

From A, pull out and add Open Door

From B, pull out and add Close Door

You can reuse this Event Interact to do many things like open doors or talk with NPCs

Compile and Save  

Go back to the First Person Map and open up the First Person Character Event Graph

We are now going to add our new Interact Input Action

Add an action event Interact

When you press interact, we want the game to check if there is anything near you that can be interacted with 

From the Pressed Exec, pull out and connect a Sphere Trace By Channel

This is going to draw a line around a chosen radius and look for actors to interact with

We want our Start Point to be our Camera since it is attached to the character

Under Components, add your first person camera to the event graph

From the First Person Camera Node, pull out and add a GetWorldLocation  node

Connect your Return Value to the Start in Sphere Trace by Channel

What this is doing is making wherever the camera is located the start position

From the First Person Camera Node, pull out and add Get Forward Vector

What this does is gets the forward facing direction of the first person camera

From the Return Value, we want to add a Multiply and multiply it by a float so we can get the range we want to search for actors to interact with.

Pull out a link from the Return Value and add Multiply

What we are going to do now is add the value to the current location value

From the Return Value of the GET World Location, pull out and add a +

Connect the output of the + node to the End of the Sphere Trace By Channel

Connect the Output of the Multiply Node to the bottom Input of the Addition  Node

We are going to convert the bottom input of the Multiple info a float by right clicking the pin

Selecting Convert Pin

Choose Float (single-precision)

Change the float value to 500

Then in your Sphere Trace, change the radius to 2

Enable Draw Debug Type For Duration

Compile and Save

 Test the game and press E

You will see the lines drawn that checks for actors to interact with

Return to event graph

Now we will make it interact with an actor

Pull a link from the Out Hit in the Sphere Trace and select Break Hit Result

You can see all the hit results that come with the trace

From Break Hit Result, pull out a branch from Blocking Hit

Connect the exec output of the Sphere Trace  to the Exec input of the branch

We can check to see if the actor that shows up has the interaction interface by pulling out a connection from the Hit Actor Node and adding Does implement interface

In the Does implement interface, select BPI_Interaction

Add another Branch

Connect the True Output Exec from the first branch to the input exec of the second branch

Connect the Return Value of the Does Implement Interface with the condition of the new branch

Drag out another link from the Hit Actor in the Break Hit Result

Add an Interact (message)

Connect True Exec Output of the second branch to the Exec input of  the Interact
