Week 7 - Progress of VR Project

We faced huge problems with hitting of the ball, the ball would not go that far with one hit and it usually gets dragged with the club. We tried to solve it, but took a long time and couldn’t figure it out. So, we decided that one of us work on this and the other one work on hand motion.

Sayed:

Task: Hand motion. I watched a tutorial. I downloaded the model object and import it to the project. I created a empty object for my left hand, made a prefab of the model. Rotate it according to VR preview. Each finger needs to be animated. With the animator component I rotate I rotate index, thumb and then other 3 fingers. I created a script that fingers should be moved with the buttons on the controller. 

Dalius:

Task: Solve the glitch with hitting the ball, set ball's max and min speed

After working hard for the solution, we asked Kasper for some help about it. 

We got some advices that we could increase Fixed Timestamp and Set Club Rigibodys Interpolite to Interpolite, but neither of those have worked. 
After 4 days of Googling things, I noticed that there is an option in XR Grab interactable Script, Movement type field, I've made the decision that I need to check this one as well and maybe this will solve our problems. And I was correct! Seems like that there is a bug in Unity (Unity Forum) , so we decided to change it to the Kinematic, that worked perfectly!
Also I want to understand what is this Movement type, I went to unity Documentation field about the Movement types, and Kinematic meant that In Kinematic mode the Rigid Body associated with the interactable will be moved such that the interactable attach point will match the interactor attach point as this is updating the RigidBody, this will appear a frame behind the visual representation of the Interactor / Controller.

And for another task, I had to set the ball's Minimum and maximum speed.


To get the speed of the ball, you had to get a Rigibody , and a velocity of it. And through the Velocity you can access the magnitude, which is the force speed.
In FixedUpdate function, I added some checks, if the ball's magnitude is higher that maxSpeed, I'm setting it to our max speed number.
And there is also another check, if the ball get's to the less speed than the minSpeed is set up, it records ball's lastPosition, and sets the velocity to 0, so that when the ball is returned to it's previous position, it stops moving.

Week 2 - Marker based AR

Image
  The second session, it was for lab hour. After a short discussion, we picked the idea from Tobias that we would develop a block breaker game. This would be based on two image targets, where one image target would be the level of the game and another the controls for the game. Block breaker game used as inspiration After the installation of Vuforia a nd set up the license, w e began by making simple prefabs with similar functions to the original and scripting some basic behavior. We managed to get the image targets working but the ball always fell when we tried to run and move it. Then we figured it out that we should set the gravity of them to 0, so that we can make it possible to control the paddle by moving the image target. Early prototype The biggest challenge we ran into was getting everything collide properly. When moving the ball and the paddle to the controllable image target, the ball would get launched underneath the objects spawned on the level image target. We tried vario

Week 6 - Progress of VR Project

Image
Week 6 started not too well, cause 2 of the group members decided to quit the group and start a new one. Since we had an idea what we want to do, we sticked with mini-golf idea, and decided to go further with the functionalities. Sayed: Task : M ovement design. Each one us created a mini golf field to start with. I started working on teleportation from one place to another. I created a teleportation anchor at first. Created XR rig. Created empty objects for my right and left controllers.  A base controller for each hand. Added XR controller action based to my base controller and set up references for each controller. Changed the ray from linear to Bezier Curve and changed the color, created a new script to activate and cancel the teleportation. If the player is seated and has not the option of turning around, we implemented a rotation method that with pressing joystick to the right or left he turns 90 degrees accordingly, and finally tested on device. Dalius : Task : Make out of bounds

Week 3 - Markerless AR

Image
This week we were presented with markerless augmented reality. The main difference between this and marker based is the need for a marker. Markerless will use the environment to try and make markers on which to project objects we want to place. The setup for the projects are easy as the packages needed for markerless AR are easily available on unity hub. The requirement for this project is to make an educational app. We decided to spend this week each working on an idea and make a small prototype to try and get a feel for markerless AR and to have something to start a project with. Here are the ideas we came up with: Tobias: My idea for a project is a history education app where the user can see real life scale models of historical weapons like the trebuchet. To make the app more interesting, we can add animations to the weapon, to allow it to go through the different stages of using the weapon. Additionally, we can add information screens for each of the stages, so the user can learn
