Collector3D! My First Ever 3D Game, Programmed in Godot!

Collector3D

Well, I finished the online YouTube tutorial by BornCG, which you can check out here. His tutorial is great and I learned a lot. I did make several changes along the way, and I used this as an opportunity to practice my work in Blender, making my own graphics for everything, as opposed to using the material he presented.

Code wise, it is the same game, but I did code several things differently, as I worked on expanding my knowledge of programming. An example would be the player ball rotation. In the tutorial, he shows how to use a variable and a set number to change the degrees to radii of the ball when it rotates.

However, This had several drawbacks. The first was that you needed to fiddle with it in relation to the variable of the ball’s speed. In other words, if you changed the speed of the ball, you would need to watch it move and guesstimate the change needed to the variable for rotation. Secondly, if you use his method, then when you stop pressing the arrow keys to move the ball, the ball stops rotating, but still “slides” until it comes to a stop.

To fix this, I changed the rendering of the ball rotation to be based off of vector speed. This makes the ball look very natural when it rolls. E.g., if it rolls forward, the degrees of roll looks naturally like the distance it is rolling over, and gives it a more realistic look. This also allows me to change the ball speed without having to adjust it’s degrees of roll. The best part, though, is when you release the arrow keys, and the ball is slowing to a stop, it now rolls, in accordance with it’s speed, slowing it’s roll as it slows to a halt in speed. It just look much more realistic.

I do believe that the author, BornCG knows how to do all this, and was just making a simpler tutorial for the viewers to follow. Or perhaps more specifically was trying to show the relationships of variables to those new to programming.

Other examples were just style points, adding timers and effects when you “die”, rather than the simple “cut to end screen” approach, and other such small things. Overall, the game mechanics and idea came from BornCG’s great tutorial. For a free resource that is widely available, I’d say this tutorial was a 5 star product, and I highly recommend it for anyone looking to start using Godot. I found numerous 2D tutorials for Godot on YouTube, but this is one of the very few 3D tutorials for Godot. Certainly worthy of your time if you are looking to start using Godot.

That said, here are some great links for my game:

* Notes: I did not try the Windows executable, since I didn’t have a Windows machine to test it on. I did try out the Linux executable on two different Ubuntu machines (17 and 18). If you try the Linux executable, be sure to chmod a+x the file so you can run it. Also, if you try out any of the executable files, be sure to comment below how well they worked and what OS you tried them on!

YouTube milestone, 1000 subscribers want to know how to build Android!

Hey everyone! Praise God! Great news! I just passed 1000 subscribers on YouTube and I just wanted to take a minute to thank all of you for taking this journey with me.

It’s a bit funny, since I thought that posting the original videos about building Android was a one time deal, and after that I would be done making them. Through your encouragement and questions, I’ve now got over 240 videos all about building android and apps.

I have a new link for my channel:
http://www.youtube.com/c/AlaskaLinuxUserAKLU

But don’t worry, the old one still works if you have it bookmarked.

I’ve got a few more adventures in android building coming up, including upgrading the BLU phone to Oreo ( I was able to boot Oreo the other day, it doesn’t work very well, but it is pretty good progress for a lollipop phone ), including marshmallow and nougat along the way.

Please keep the questions and suggestions coming in, as these help me understand what videos I should focus on next. Down the road I hope to make some videos on building without ninja and jack, as well as building generic system images ( gsi ). Thanks again everyone!

Video Tutorial for Building Android: Advanced Topics

twrp
Praise God! Another video series featuring more advanced material!
Previously, I had created a video tutorial and guide for how to compile Android, from Lollipop through Marshmallow, Nougat, and Oreo. If you need help learning the basics or intermediate material, please see my other video tutorial thread on XDA, Or here on my website through the navigation bar at the top.

Who is this video series for?
Well, this video tutorial is a guide built primarily for the intermediate Android developer. This is written for those who already know how to compile custom roms for a phone that they own using device trees and vendor files that are already available. Things like using git, GitHub, GitLab, ADB, fastboot, and repo sync should already be something familiar to them.

That said, I believe that an intermediate developer will find this set of videos to be most helpful. The goal of this video series is to push the intermediate developer up to a rudimentary advanced level.

Advanced developer?
An advanced rom/kernel developer will probably far exceed my feeble abilities, and will not likely find much useful information here. Perhaps if you are an advanced developer, you would consider making another tutorial or adding to this advanced video series! (See further posts for recommendations on contributing videos.) Please! I’d really like to add links to your YouTube channel, or your git repository full of advanced topics for developers! Help up the quality of devices and builds of Android by showing others what you know how to do best!

Why did you put this together?
Well, after releasing the previous tutorial, explaining to beginners how to use things like git, repo sync, compile roms, and do small kernel modification, it was brought to my attention that a more advanced course was needed for intermediate users who already know how to build roms, but may (like myself) struggle with more complicated tasks. I don’t know how to do everything, and we all have to take the next step sometime, so why not take that next step together?

What’s in the videos?
During the series, we will be attempting several more advanced tasks. At present, there is not a lot in the series, but below are some of the highlights from what is available.

  • A: Building a device tree from scratch
  • B: Upgrading a device from Marshmallow to Nougat
  • C: Creating your very own custom rom!

Section A: Building a device tree from scratch:

+ Research
+ Finding similar devices
+ Pulling vendor files
+ Setting up a device tree
+ Getting block device information
+ Pulling kernel information
+ Breaking down boot images
+ Build errors
+ Target Assets
+ Tombstones AND MORE!

Video Tutorial on How to Compile Android and Modify Kernels

video

For those interested, I have just posted a video tutorial series on XDA for building Android Oreo, Nougat, Marshmallow, and Lollipop on 5 different phones, the emulator, and 5 different ROMs. Also included are custom kernel editing, adding apps, changing source code, backgrounds, and more. Here’s what I posted:

From XDA: https://forum.xda-developers.com/android/general/guide-how-to-build-custom-roms-kernel-t3814251

===========================================================================

Praise God! Finally a video tutorial of how to build Android and modify kernels!

I have created a video tutorial and guide for how to compile Android, from Lollipop through Marshmallow, Nougat, and Oreo. The video series covers several different phones, the emulator, kernel and rom editing, app source code editing, and much more!

Who is this video series for?
Well, this video tutorial is a step by step guide built primarily for the beginner. This is written for those who already know how to flash TWRP, CWM, or the like, and who have installed a custom rom before. This is designed to help those who are ready to move up from flashing and installing other peoples custom rom to actually start making their own custom roms. I recommend that a beginner watch the entire series in numerical/alphabetical order (the videos are marked).

That said, I believe that an intermediate developer may find a useful trick here and there, and they should just skip ahead to videos of interest. Perhaps kernel development, or something along those lines.

An advanced rom/kernel developer will probably far exceed my feeble abilities, and will not likely find much useful information here. Perhaps if you are an advanced developer, you would consider continuing the tutorial or making an advanced video series! (See further posts for recommendations on contributing videos.)

Why did you put this together?
Well, after building roms for several different devices, I started receiving requests from users who wanted to start building their own roms, but didn’t know how. I didn’t have enough time to answer everyones questions, so I wrote a few guides, pointed others to guides that were available, but there are some things that you just need to see to understand. Hence, the video tutorial. I just hope that someone finds it useful.

This course was written in order! While Lollipop and Marshmallow are old by today’s standards, there is still good learning value in building them, and there are topics covered there that really make them worth watching.

What’s in the videos?
During the series, we will be building for the emulator, as well as 5 different phones of various brands, and 5 different roms. I hope that this will give the viewer a good idea of how to build for their own specific phone as they see the differences and similarities across the phones and custom roms.

[CODE]
+ Ubuntu installation
+ Java installations
+ Using Git, GitHub, GitKraken, and the command line
+ Fastboot and ADB
+ Heimdall/Odin
+ QFIL, QPST, SALT, and other tools
+ AOSP, SlimRoms, PACrom, AOKP, AOSCP
+ Lollipop, Marshmallow, Nougat, Oreo
+ Errors
+ Overclocking CPU/GPU
+ Adding Governors and I/O Schedulers
+ Sound modifications
+ Changing app colors, text, and icons
+ Adding prebuilt apps
+ Adding source code
+ Converting device from one rom to another
+ AND MORE!
