In Topic: Questions for a tester.

So the question is - are you truly at the Beta stage considering the questions you have mentioned up top? If you aren't then by all means suck every drop of feedback you can obtain.


I guess it's slightly both. We're preparing a demo to show off but I also want to get players impressions of how the game generally feels. 

So perhaps alpha would be a better term for this.




Any tips on what to google search? I have listened to some GDC talks before on the subject but never have found any questionnaires specifically for games

with the exception of club nintendo.

So the game is a platformer for mobile that is using a non virtual joypad control input and it will be coming out for both iOS and Android. It's

has the general theming of a Mario game, so not dark like a Castlevania title.


The only other person that is working on the title is my girlfriend and I believe most of the people that are coming are going to be game 

devs from my local IGDA chapter. We're also doing this at a local café so we may not be able to get webcam stuff going.


Also how many questions might be too many? We have them going through three levels that are approximately a minute and a half each 

so I don't want to overload them.

The problem is when I put it to TEXCOORD1 it doesn't draw the thing at all. I'm trying to have it make a mask on the rendertarget to make it round.

In Topic: Using XNA RenderTargets

As far as I know, there are just some performance considerations with the Xbox and rendertargets. In XNA 4 they apparently changed the interface so that behavior (but not performance!) is the same across platforms. The usual advice is to get something working first, then make a determination if optimization is needed.

Of course, as I said, I'm not really the expert here, so maybe someone else can give a more detailed or accurate answer.

So I figured it out!

Here's the code so if anyone is doing something like this they can use it! Please though just site me in the credits as a Special Thanks and let me know :D

            spriteBatch.Draw(finalTexture, new Rectangle((int)position.X, (int)yPosition, 100, 100), Color.White);

And then here's the Mask HLSL Code

texture spherePort;
texture mask;

sampler TextureSamplerSphere = sampler_state
	Texture = <spherePort>;

sampler TextureSamplerMask = sampler_state
	Texture = <mask>;

// TODO: add effect parameters here.

float4 PixelShaderFunction(float2 TextureCoordinateSphere : TEXCOORD0, float2 TextureCoordinateMask :TEXCOORD0 ) : COLOR0
    // TODO: add your pixel shader code here.
    return tex2D(TextureSamplerSphere, TextureCoordinateSphere) * tex2D(TextureSamplerMask, TextureCoordinateMask);

technique Technique1
    pass Pass1
        // TODO: set renderstates here.

        PixelShader = compile ps_2_0 PixelShaderFunction();

Thanks for the Help :D

No I haven't but doesnt that cause issues with the Xbox 360?
