Shaders project vertices from a cubical shell onto a spherical shell to avoid singularities. Then a coherent 3D noise function is used to define radial perturbations whose magnitudes index into a 1D colormap with black, red, orange, yellow, and white.

AdaGate Brief Game Description

AdaGate is a strategy game with escape rooms in a Stargate fantasy setting. It is an elaborate example of modern OpenGL programming using the Ada language; and a tribute to Narbacular Drop, and Amelia Earhart.

Each room has a barrier that must be circumvented using portals. The barriers include water with piranha, molten magma, and walls.

Runs on Windows, OSX, and GNU/Linux. The linux binary now runs on many linux distros! Includes all source code, build scripts & resources.

AdaGate Detailed Introduction

While searching a remote south-seas atoll for remnants of a lost American heroine, you find a nearly operational stargate. If you can get it working, you will be transported into an off-world temple with multiple chambers. You'll need to power up the exit gates & portal systems in those chambers by rolling ZPM power cells onto their sockets. Simple, right? In order to do that you must solve a sokoban puzzle, which means there is a correct sequence and a correct pairing of ZPMs to sockets (and many wrong ones). When all the ZPMs are all engaged they will light up and a portal gun will appear. Use it to create portals that bypass the obstacles so you can reach the exit stargate.

Caution: solvability of the powercell puzzles is guaranteed only when jumping in on the "@" symbol. Moreover, cheating by jumping out is impossible because of a gravity lock.

Escape all four chambers to ascend...and catch a glimpse of Amelia; whence the level of difficulty is increased for your next game.

AdaGate Game Features

• Works on PCs or laptops running Windows, OSX, or GNU/Linux. And if Ada is installed you can rebuild it yourself! But first try the binaries that are delivered for all platforms.

• Windows, OSX & Linux binaries provided, as well as full source.

• Laptop friendly controls; supports HiDpi displays.

• A 3D Sokoban puzzle game that uses the intersection of two cylinders as a puzzle piece that rolls in two perpendicular directions.

• Stargate dial-home-device [DHD] allows non-linear play; see the island setting evolve from sun to fog to evening to night.

• Roll the ZPM power cells to empower the portals and escape thru a wormhole

• Four rooms and five degrees of difficulty for a total of 20 challenging puzzles. And solutions are available in the file ./data/solns.sok.

• Serves as a blueprint for modern OpenGL programming in Ada or C++ using GLSL 330, shaders, uniforms and textures.

• Note that Sangwine's PNG-IO library, and the Ada bindings to OpenAL, OpenGL & GLFW3 in this app constitute a complete, yet easily extendable Ada library that could be used for most any modern OpenGL project including games, animations, simulations, modeling, or engineering.

• The sound system enables a build with surprising portability across various linux distros, as well as across various platforms.

mouse/touchpad/keyboard controls

[You might need to disconnect unused gamecontrollers to prevent spinning!]

Look direction is controlled by touch pad or mouse; The mouse wheel controls camera zoom. On laptops, a 2-finger swipe simulates the mouse wheel; Zoom can also be controlled with keys n, f, z [Nearer,Further,default];

Movement is controlled by the WASD keys or the arrow keys:

		(Up)
(Lt)	(Dn)	(Rt)

Shoot the two portal guns using: l-key r-key, or (if you have two) the two mouse buttons.

• (space)-key => jump up/over short walls

• (esc)-key => exit;

• m-key or (F1)-key => toggle between mouse-view (1st-person) or avatar(3rd-person)

• q-key => Quiet...stop the music

• h-key => show Help screen

---

If a tricky ZPM puzzle has trapped you, it is now possible to reset it. Typically you need to jump up and out of the sokoban grid, then reset, then jump in @ proper place. These 2 new [experimental] key combos help to reset a ZPM puzzle that has trapped you:

• (ctrl)-l => release the gravity Lock
• (ctrl)-r => Reset ZPM puzzle

...otherwise simply restart the game and go back to the dungeon where you will encounter a re-initialized puzzle.

---

In case of control problems with the game, or if you want to easily inspect something, use 1st-person mode.

joystick

• joystick : attitude
• center thumb btn: forward
• trigger btn: backward
• Ltop/Rtop btns: select/shoot
• 1st base btn: jump

gamecontroller

• Lpaddle/Lhat : attitude
• Rpaddle : movement
• L/R Shoulder btns: select/shoot
• 1st Dpad-down btn: jump

controller settings

If the need arises, copy the file "docs/default_settings.txt" to "data/settings.txt". Then you can manually edit the floats that define the sensitivity for mouse, keyboard, gamepad & joystick, as well as forward speed of the avatar. EG: Forward speed was recently increased by 25%; if you prefer the old speed, change the first value from 1.0 to 0.75.

---

If you ever get stuck, try to jump up + forward or back.

System requirements for running delivered executables:

• graphics card with ample memory & updated driver that supports OpenGL version 3.3 or later.
• Windows, Mac OSX(>=10.13), GNU/Linux;
• optional game controller or joystick.

Note on Intel embedded graphics

• Such hardware uses system RAM; 8Gb is enough to run but the drivers I've experienced exhibit annoying flaws, although the game is still playable.

Setup & Running Adagate:

The application's main directory [./agate/] contains files for deployment on 2 platforms: 1)windows, 2)linux, in addition to source code. If you are NOT running windows, you do not need .dll files.

Windows users see also: "windows-setup.txt"

Unzip the archive.

• On Linux & Windows, 7z [www.7-zip.org] works well for this. The proper command to extract the archive and maintain the directory structure is "7z x
