Week 6: VR Implementation


 Beat Saber Implementation

This week, we started by creating the floor and a room using cubes. To get the color of the room in black from the inside and outside, we set the material settings to this:


We also added some lines to the scene to make the room look pretty:


Now we create the boxes that the player will hit, and we tried to make them look like the ones in beat saber:




Both boxes are prefabs so we can spawn them in the game.

Now we need the boxes to move forward, so we create a script for the boxes and under the update method, we add a line of code that will do so. Here we are using a velocity of 2 meters by second, by multiplying the position by time.deltatime by 2:


So we add the Spawner, we do so by adding an empty GameObject and add a new script to it. The Spawner script will have the logic to spawn the boxes.



The script will have two arrays, one with the boxes prefabs, BLUE and RED, and one with the place holders of where the boxes will be spawned from. It also has the beat, which is the duration of every when should a box be spawned, and the timer will count the time remaining between two beats and between the spawn of the cube.

In the Update method, we check if it’s time to spawn a new box, if it is, we randomly select the spawning box so the box would be either blue or either red, and also randomly select which place will the box be spawned at. We also add a rotation to our cube using a rotate function and the rotation will be random so the cube will be either right, left, up, down. And we end the update method with updating the timer and adding the deltatime.

Now we create empty GameObject in the scene and these will be the places where the boxes will be spawned at. They will be under the spawner GameObject.


Now we add two new layers, one for blue and one for red, we do that so we can distinguish the red boxes from the blues ones, once we hit them with the saber. So the blue box will be in the blue layer and the red one will be in the red layer. 

Now, it’s time to create the sabers and their logic. So the player will have two sabers, one in blue and one in red, and the players should use the sabers to hit the boxes according to the color. So red hits red and blue hits blue.

So we create the two sabers as cubes, and we add this script to them:


Now that the scene is almost ready, we add the VR setup from last week into this project. We add the OVRCameraRig to the scene, which has the cameras and the controllers anchors.

We move the left blue saber to under LeftHandAnchor, and the red one to under RightHandAnchor.

Next week it will be the time to see if it’s really working.

Week 4: Markerless Implementation and Finalisation

Image
Markerless Virtual Worlds At this point, we have some of the project done and running, such as detecting planes and displaying the portal on the new plane, now we have to work on travelling to Paris when the user enters the portal. First, we start by finding a suitable 360 video, that we be the virtual world behind the portal. We found a video that is about Paris and it shows the main attractions there plus captions of what landmarks they are showing at the moment, which is really cool, so we downloaded it and imported it to the assets in our project. Our goal now is to add the video to the scene, and since it’s a 360 video, a sphere is perfect to have the video playing on the circumference of the sphere.  So we created a sphere and we scale it up to 50, so it becomes the new virtual world. We attach a Video Player component to it and add our video as the Video Clip. Now, the video is playing on both sides of the portal, but we want it to only play on the other side, to do so, we s...

Week 3: AR Final Result

AR Brick Breaker Finalisation  This week we finished the project, Kasper recommended using velocity on FIxedUpdate() so the function will be executed periodically while our game is running.  This fixed our problem with the balls’ behaviour, we also angled the side walls so we wouldn’t end up in an infinite loop. This is a video showing the final result:

Week 10: Project finalization

VR Escape Room  Finalization We tried many ways to make the buttons pressable, and only one way worked for us, which is by using animations. So we started by creating the animation, which is a simple change in the position of the button.  Then, we only want the button to animate if the player presses it, so we need a trigger to start the animation. After creating the button’s animation, we double click on the animator to get its window. By default, the animator will look something like this: Which means that as soon as the button is instantiated, the animation will start. But we wanted to only start when the player presses it. So we replaced the default state of the button with a new empty state that we just created and we set it as default. Next thing is to create a transition between the new default state and the ButtonAnimation, and also the transition between the buttonAnimation and the default state, so, back and forth. We also create a boolean parameter to the animator t...
