  • Hi I am trying to learn basic js with construct - in the attached file, how would I instance player1 100 times, and set each instance to a 10 x 10 grid?

    thanks much

  • Hi Jsea, I'm new to C3 so I may not be the best person to answer your question, but try adding this to your for loop: 

    const randomNumberX = runtime.random() * 450;
const randomNumberY = runtime.random() * 450;

runtime.objects.player.createInstance(0, randomNumberX, randomNumberY);
	
// Or
	
// const clone = runtime.objects.player.createInstance(0, 0, 0);
	
// clone.x = runtime.random() * 450;
// clone.y = runtime.random() * 450;

  • thanks! heres my grid! It's gorgeous!

    If I have one object called enemy, how do I get/set position? I tried

    runtime.objects.enemy.x,runtime.objects.enemy.y but it gives me undefined.

    thanks! 

    runOnStartup(async runtime =>
{
	runtime.addEventListener("beforeprojectstart",() => OnBeforeProjectStart(runtime));

});

function OnBeforeProjectStart(runtime)
{
	runtime.layout.addEventListener("beforelayoutstart",() => OnBeforeLayoutStart(runtime));
	
}

function OnBeforeLayoutStart(runtime)
{
	
	console.log(runtime.objects.enemy.x,runtime.objects.enemy.y);
	
	for(var i = 0;i<10;i++){
		for(var j = 0;j<10;j++){
		runtime.objects.player.createInstance(0,i*32+32,j*32+32);
		}

	}
	
}

  • Glab I could help! Your grid is magnificent ; )

    To set and get the position of an enemy you could try this. 

    runOnStartup(async runtime =>
{
	runtime.addEventListener("beforeprojectstart",() => OnBeforeProjectStart(runtime));
});

function OnBeforeProjectStart(runtime)
{
	runtime.layout.addEventListener("beforelayoutstart",() => OnBeforeLayoutStart(runtime));
}

function OnBeforeLayoutStart(runtime)
{
	//g_playerInstance = runtime.objects.Player.getFirstInstance();
	var Player1 = runtime.objects.player.getFirstInstance();
// 	console.log(Player1.x);
	for(var i = 0;i<100;i++){
// 	console.log(i);

// 		runtime.objects.player.createInstance(0, runtime.random() * 1280, runtime.random() * 960);

	const randomNumberX = runtime.random() * 450;
	const randomNumberY = runtime.random() * 450;

	runtime.objects.player.createInstance(0, randomNumberX, randomNumberY);
	
	// Or
	
// 	const clone = runtime.objects.player.createInstance(0, 0, 0);
	
// 	clone.x = runtime.random() * 450;
// 	clone.y = runtime.random() * 450;
	}
	
	const enemyOne = runtime.objects.enemy.createInstance(0, 475, 275);
	
	const enemyOneX = enemyOne.x;
	const enemyOneY = enemyOne.y;
	
	console.log("Enemy X: " + enemyOneX + ", Enemy Y: " + enemyOneY);
}

  • Insane!

    Thanks DFORM!

  • You're welcome.
