Game++. Part 1.4: Game engine architectures by cli345 in c/gamedev@programming.dev
[-] cli345@programming.dev 1 points 4 weeks ago* (last edited 4 weeks ago)

I like this overview.

The gameplay loop is what unites all games and game engines, although it may be veiled within the engine, replaced by abstractions or handler functions (callbacks). (Part 1.1)

Incidentally, in my view, it reproduces the common belief that a game has to be structured as a main loop that might be hidden to the programmer in which case s/he has to associate actions(handler functions) to events. This example attempts to prove that it's not always the case.

FuncSug: I intend to adapt it for Godot (github.com)

Hello, ๐Ÿ™‚

I created a new language called FuncSug. Its purpose is to make GUI programming in the browser easier and so game programming. The facility consists on eliminating asynchronism: In FuncSug, the code is no longer managed by an implicit/explicit global loop (I don't speak about implementation).

I intend, if I have time, to implement it for Godot as well. In FuncSug, the first tutorial of Godot would be roughly coded as this:

func showMessage(p_message):
	parallel exitWith branch 2 ||
		showIn(p_message, $MessageLabel)
	||
		waitSeconds(2)

parallel ||
	while true:
		# Start of game
		parallel exitWith branch 2 ||
			showMessage('Dodge the\nCreeps')
		||
			waitSeconds(1)
			awaitPressed($StartButton)
		get_tree().call_group(&"mobs", &"queue_free")
		score := 0
		$Player.start($StartPosition.position)
		
		# Middle of game
		parallel exitWith branch 1 ||
			awaitSignal('hit')
		||
			while true:
				playSoundFile('House In a Forest Loop.ogg')
		||
			showMessage('Get Ready')
			parallel ||
				while true:
					waitSeconds(1)
					score += 1
			||
				while true:
					waitSeconds(0.5)
					callgd spawnMob()
		
		# End of game
		parallel ||
			showMessage('Game Over')
		||
			playSoundFile('gameover.wav')
||
	while true:
		await score
		$ScoreLabel.text := score

The 'player.gd' and 'mob.gd' files would be keeped as they are. The "_on_MobTimer_timeout" function would be renamed as "spawnMob" and moved to 'mob.gd'. The timers wouldn't be needed any more.

Can you tell me what you think about it?

Here, for example, is how the showMessage function would work:

  • $MessageLabel is a field defined by the programmer in Godot.
  • The showIn(p_message, p_place) function shows the message p_message in the field p_place.
  • waitSeconds(2) waits 2 seconds.
  • When the 2 seconds are elapsed, the second branch waitSeconds(2) is finished and so the parallel block is exited (because of exitWith branch 2) and the other branch (the first one) is definitely interrupted (because my parallel exitWith branch N does so).
  • The interruption of the first branch showIn(p_message, $MessageLabel) makes the $MessageLabel invisible.

Yes, it's very different from what is done in G'MIC. Here, the language is preferably adapted to user interactions. There aren't many in G'MIC. ๐Ÿ™‚

Yes, that's why I hope others will be able to join me. In the meantime, you can try FuncSug in the Playground. ๐Ÿ™‚

Thank you for your very useful feedback :)

A native representation of HTML tags is a good idea: I'll have to do that.

For ...---, I wanted a big split symbol between branches (||========) and a small split symbol between the two steps inside a branch (...---). ... because the branch continues and --- to mark a smaller split than ==========.

I intend to add a syntaxic sugar for:

parallel(select N) ||
||==============
	myFunction(arg1,...,argM)
...--------
	restOfBranch1
||=============
	myFunction(arg1b,...,argMb)
...-------
	restOfBranch2

that would be:

choose N by myFunction
	* arg1,...,argM
		restOfBranch1
	* arg1b,...,argMb
		restOfBranch2

Hi, I made FuncSug to make GUI programming in the browser easier. It's a new language that aims to enable a clearer and easier code structure.

Can you tell me what you think about it?

This is just a very naive execution model for concurrency.

What do you think about it?
