Blog - JSE - GameHandler

20th June 2021

I finally did that mini writeup of the GameHandler function, today.

-=-=-

I've been putting it off for a while, as I kept adding in little nips and tucks, but today I've decided that enough's enough, and just finished the whole thing off.

GameHandler("Game Title","Easy|Normal|Hard")
is more or less enough to get the menu going.
From there, add an .Ingame subroutine, and be sure to return each frame, whilst keeping your game ticking away. Keep track of a Score variable, and it'll pop up on the highscore table.
The EndGame command does just that, and returns the player back to the menu, adding the latest score to the scoreboard, saving the current high scores, and so on.

// GameHandler Example
// Mouse Clicker

Symbol 0,"0__4?0,4.0.4.0.4?0,4004,0!4,0!4,0!44";

Graphics 512,512,1
SetHandlerFont "Labyrinth"
GameHandler("Mouse|Clicker|2000","5 seconds|10 seconds|15 seconds")

.StartGame
Score=0

	// Change the time limit based on the menu option selected.
	If GameType==1 then TimeLimit=Mills(1)+(5*1000)+999
	If GameType==2 then TimeLimit=Mills(1)+(10*1000)+999
	If GameType==3 then TimeLimit=Mills(1)+(15*1000)+999

Return

.Ingame
CLS;ResetDraw()

	TimeLeft=Floor((TimeLimit-Mills(1))/1000)
	If TimeLeft<0 then
		TimeLeft=0
		If GameOver==0 then PlaySFX("Beeper_Fruit_Win")
		EndGame "Time's Up"
	Endif
	Text ScreenWidth/2,ScreenHeight/2-64,TimeLeft,1

	// A Click
	If MouseHit() and GameOver==0
							// GameOver increases once EndGame has been called
		Score=Score+1
							// Score is used by the Highscore system
		PlaySFX("Beeper_Coin")
		ThrowParticle MouseX,MouseY,2,Rand(-45,45),Rand(2,5)
	Endif
	TextScore ScreenWidth/2,ScreenHeight/2

	Text ScreenWidth-16,16,"Score to beat "+Highscore,2
							// Highscore is the topmost score on the current leaderboard
Flip
Return

The Mouse Clicker 2000 example should help you figure the rest out..
.. Maybe!?!
There's more info in The Help Files

Meanwhile..

A few extra new commands have been added.
GetRed(), GetGreen(), GetBlue() and GetAlpha() return the currently set colour values.

TextScore x,y displays the value of the variable Score onscreen, centred at x,y, using the current colour/size/etc settings.
