Open Golf

A cross-platform minigolf game written in C.

Platforms

• HTML: https://mgerdes.github.io/minigolf.html (Works best in Chrome)
• iOS: https://apps.apple.com/us/app/open-golf/id1615224465
• Android: https://play.google.com/store/apps/details?id=me.mgerdes.open_golf
• Windows
• Linux

Info

• Used the Sokol libraries to create a cross platform application with 3D graphics and audio.
• Wrote the Physics code to handle collision detection and collision response for the golf ball.
• Used ImGui to create in games tools for fast iteration. Also created an in game-editor that can be used to modify the terrain of a hole and then quickly play to get fast feedback. The game-editor can also run scripts to generate the points and faces of more interesting models.
• Used the library Lightmapper to generate lightmaps for the terrain and also xatlas to generate lightmap UVs. These lightmaps are then baked into the files for the courses. It can also interpolate between multiple samples to create lightmaps for some moving objects.

Building

Windows

• To compile run build\build-win64.bat

• To start the game run out\win64\golf.exe

• This also creates out\win64\golf.sln which can be opened in Visual Studio to compile / run everything

Linux

• To compile run ./build/build-linux.sh

• To start the game run out/linux/golf

OSX

• To compile run ./build/build-osx.sh

• To start the game run out/osx/golf

open-golf's Issues

Share your best moves

I really like your game.
When you make a great shot, you are very happy but you can't share it, it's a bit frustrating I think.
A way to make the game known in a viral way would be to share your best moves on social networks for example.
If the game recorded the games and allowed the player to share them when he is satisfied with his move for example:

golf.mp4

Android: wrong position of clicks

Phone: Samsung M31
Play store release (mar 22?)

When I click on play button, nothong happens.
When I click inch or so above, level selection starts.

I can scroll level list in higher location than window suggests.
Tap area for level selection also higher than it should be.

I cannot find point to hit a ball, I can only rotate camera around.

I think this is related to DPI or rotation, but no idea how to fix or work around it.

Flatpak package?

Hi! Are there any plans to provide a Flatpak package of Open Golf? It would make it easier to install on Linux. It could also be nice to have it published on Flathub, which would make it available in the default store apps of many Linux distributions.

Feature: Quick-Retry

I have a lot of fun playing the game (iOS), but one thing I've noticed: retry is a bit slow. When hunting for the best scores, you retry a lot and two things become frustrating:

1. The pause button to access retry is only triggered when the ball has stopped rolling.
2. The unskippable intro camera movement plays again upon retry and makes the player wait.

It would be nice if retry was as quick as hitting an out of bounds object.

Mute sound

Add a button to mute the sound while playing.

Build error on macOS

Following your build instructions, I get an error with sokol. I think it wants to have a gfx option defined somewhere:

Can't control the ball

This is from level 7, when i move my ball to this position then the ball keep being pushed by the water and the wall so that i can't control it.
I love the game and some how this inspire my a lot. Thanks

video.mp4

release to f droid + put .apk on github for obtainium

Show best score for each hole

On Android (haven't tried other platforms) the best score for each hole is displayed on the menu screen. However when playing through the game, there's no indication of what the current best score is for each hole. I think this'd be handy as it'd allow you to see what score you need to beat on subsequent playthroughs.

Crashes when releasing ball

I can build and run the app, but when I release the mouse to launch the ball the app crashes.

Here's a backtrace

SIGSEGV when opening on Android

Launching the app (the 1.0 version from F-Droid) on an armv7l LineageOS 14.1 (Android 7.1.2) device results in an immediate SIGSEGV with only the Android crash dialog being displayed. The backtrace implies it might be some kind of audio issue.

Infinite void

In the last hole, where a barrier pops up before a C-shaped loop, it's possible to hit the ball over the background mountains into an infinite void. The game doesn't continue.

Add more courses

I enjoyed the 20 courses that come with Open-Golf. After playing through all of them I would like to see 20 more.

Ball releases when finger leaves game window

One of the constant annoyances I have with this game is that when my finger is aiming the ball with maximum force, if my finger moves too far down the screen and leaves the game window, the ball releases prematurely.

I'm not sure if there's a way to fix this, or if it's by design...

Apple App Store Age Rating Incorrect

Thanks for the App. We think it's fun!

Recently the rating for this app changed to 17+ on the App Store. This seems to be incorrect. Previously my pre-teen son was able to play it on his iPhone, but now cannot because of the age restrictions. Can we get this changed? (Not sure you have any control over it...)

Thanks!

Add to F-Droid

F-Droid is a FOSS app store for Android. I suppose that your app is a good candidate to be freely released there

Great app!

This is an awesome app! Please add more levels. Its by far one of the best golf experiences on an android device.

Isnt runnning on Linux

Thats the errors

System:
Ubuntu 21.04
dwm/xorg

A level editor

The game is very good, but unfortunately it's quickly over.
If players could create levels and share them it would be really great and it would increase the life of the game considerably.

How to access editor

yup, thats my question

A ranking of the best players

In order to increase the spirit of competition there could be some sort of ranking of the players.
For example by using the number of moves per level and the time used to complete the stroke, and the player's nickname.
