What do you need help with? Version 5

[Jimmylaw]

Using C++ and directx, What would be the best method of loading in a shader and then giving it to different entities? The method I have right now works but If i attempt to change a variable in one of the entities, the same variable changes on the other entities.

I'm trying to multiply the value of my chronometer or just try to get the value to be a string.

Every time I try to make it a string and use toast.show() to view it, my application crashes. I can get the value of my EditText to show up but I can't seem to get my chronometer to work. Both the strings time and fin make it crash. Here's the code:

String hour = String.valueOf(mText.getText());
String time = String.valueOf(mChronometer.getBase() - stoppedMilliseconds);
int h = java.lang.Integer.parseInt(hour) / 60;
int t = java.lang.Integer.parseInt(time) * 1000 / 60;
int mm = h * t;
mon.setText(Integer.toString(mm));
String fin = "" + mm;


Toast.makeText(PoopActivity.this,
        "Money made: " + fin, Toast.LENGTH_LONG).show();

I would say paint. I have tried dozens of programs and all of them are hard to make diagrams as you want them. Someday I might make my own program.

[QUOTE=Richy19;36812197]Dia[/QUOTE]

Maybe I am dumb, but I find it a bit hard to use. It is still one of the best programs that you can use for this.

Are you sure, looks like mon is the reason for it to crash. If mon is null, you cannot call setText.

Writing raw structs into files only makes sense if they're never going to change and even in that case you should serialise them.

[AlienCat]

Thats right, just dumb of me to suggest that.

Anyone know something about qt3d? I can't for my life get rid of the culling or whatever it is called. When zooming towards a object, it got like eated by a black border. setNearPlane does not help.

Here is some code:

{
    QGLCamera* cam = new QGLCamera();

    cam->setNearPlane(1);
    cam->setFarPlane(1000);

    painter->setCamera(cam);

Notice the rt_w & rt_h variables there.

and I:
Draw things to the window,
Draw things that need blooming to FBO1 with normal shader.
Draw FBO1 to FBO2 using the first shader.
Draw FBO2 to window using second shader.

So my idea was to reduce the size of the FBO's by 4 giving me FBO's of size 256x144 but when I use the same code but simply reducing the FBO size doesnt draw it, can someone help me out with what values the FBO's, Perspective & Ortho matrixes and displayImage's should use in terms of height and width?

[Lord Ned]

I thought you were supposed to render your scene out to the Backbuffer/a Texture2D, downsize it in steps (halving each time until it's a certain size), apply a gaussian blur to the downsampled image, then upscale that and apply it over the original backbuffer with certain blending modes.

Having problems with GLuint and GLint with C++/OpenGL. Just getting errors like,

I'd like to make maps in a neat fashion so I can also place crates and buildings on them, however the only way I have been managing to do this is by giving eat block a value (ei 1 = block 0 = air) and filling in a grid, which works to an extent, but its nothing pretty and I can't place anything else on it.

Congratulations, you're making a tile-based game.
For objects that you can move around / shoot at / are dynamic in any other way I'd recommend making an additional array for them with x and y values.
If they're just static, use other numbers, like 0 = air, 1 = dirt, 2 = crate, 3 = building-left wall, 4 = building-right wall, 5 = building-top wall etc.

[FreddiRox!]

OK, so lets say I still want to make a 2D side scroller, how else could I make the maps for the levels?

[Armandur]

Would this:

[cpp]
bool t = inputs[0]->getConnection()->output();

for(int i = 1; i < inputs.size(); i++)
{
if(!inputs[i]->getInverted())
{
t = t && inputs[i]->getConnection()->output();
}
else
{
t = t && !inputs[i]->getConnection()->output();
}
}

if(t)
{
return true;
}
else
{
return false;
}
[/cpp]

work for getting a correct output from an AND gate with 2-Many inputs, which any one of them can be inverted?

[cpp]
inputs[i]->getConnection()->output();
[/cpp]

is used for getting the output of another gate. For testing I have two types of non-standard gates: GateType::HIGH and GateType::LOW. These output true and false respectively.
