Breakout tutorial on iPhone

by Andrew Poquette · in iTorque 2D · 04/21/2010 (9:02 pm) · 27 replies

Hello all! I'm trying to convert the Breakout tutorial(Part 1) to the iPhone, and I can't seem to get the ship to move when clicked. I have double checked that everything in TGB is set correctly, and it is.

Here is my code in game.cs:

function sceneWindow2D::onMouseMove(%this, %modifier, %worldPosition, %mouseClicks){
		movePaddle(%worldPosition);
		
	}
	
function sceneWindow2D::onMouseDragged(%this, %modifier, %worldPosition, %mouseClicks){
		movePaddle(%worldPosition);
		
	}
	
function movePaddle(%worldPosition) {
		%newXPos = getWord(%worldPosition,0);
		if (%newXPos < 0) { %posmod= -1; } else { %posmod = 1; }
		if (mAbs(%newXPos) > 65) %newXPos = %posmod * 65;
			
		$theBase.setImpulseForce((%newXPos)*$vmod,0);

		sceneWindow2D.setMousePosition("0 0");	
	}

The image map for the base is set to Class: baseClass, and Name: theBase

I finally figured out how to get the images to show up (by copying the image map from the managed file) but I can't seem to get this to work. I've been researching and trying all night, but any help is much appreciated.

Thanks,
~Andy

Sure, I will upload it. Not sure how to do that yet, but I'll figure it out. BTW, I didn't optimise anything, and I didn't worry about making graphics power of 2 etc, I just ported it blindly, and it still runs on my Ipod Touch v2 very smoothly (40 to 50 fps). For a simple example, optimisation isn't an issue, and it just goes to show that the GG example is misguided. Optimisation is important, but it's a trivial problem compared to getting used to the engine in my opinion. Optimisation becomes obvious after you have a good feeling for the engine.

I'm using all of the original graphics and particle effects, and it runs great.

I was hoping to write a tutorial, but hopefully the source code will be a good help to everyone new to iTGB. Where do I up load it to?

Mark

You can email me the source zip file and I will host it on my webserver. I will email you the link when I have it online.

Hi Dean,

I've emailed my code. I've also included a ReadMe.txt file, which explains some of the changes that I made, and why I made them. I only made a few small changes though, so it's still very much like the original.

Hopefully the code will be useful.

Thanks,
Mark

Thank you Mark and Dean for helping out tremendously with n00bs like me.

Hopefully I have time tonight to digest and see what I'm doing wrong.

Got the file. Everything works, thanks Mark and Dean.

My question is:

Can you use the touch controls without having to create the sliderPadClass? Can you just use baseClass and call movePaddle(%worldposition)?

Yes, you can do that. Actually that was what I tried first, but the problem I found is that if the touch area is too small it makes it difficult to drag the object, because the finger keeps sliding outside of the touch area. I added the touchpad so that you can easily drag the base around without needing to be so precise with the finger position.
