Abstract implementation of tonal curves for RGB, Red, Green and Blue channels with three fixed nodes: highlights, midtones and shadows. Can be used to adjust overall contrast or create advanced color filters.

Parameters:

• RGB Highlights : Positive values brighten overall highlights, negative values darken overall highlights.
• RGB Midtones : Positive values brighten overall midtones, negative values darken overall midtones.
• RGB Shadows : Positive values brighten overall shadows, negative values darken overall shadows.

• R Highlights : Positive values tint highlights red, negative values tint highlights cyan.
• R Midtones : Positive values tint midtones red, negative values tint midtones cyan.
• R Shadows : Positive values tint shadows red, negative values tint shadows cyan.

• G Highlights : Positive values tint highlights green, negative values tint highlights magenta.
• G Midtones : Positive values tint midtones green, negative values tint midtones magenta.
• G Shadows : Positive values tint shadows green, negative values tint shadows magenta.

• B Highlights : Positive values tint highlights blue, negative values tint highlights yellow.
• B Midtones : Positive values tint midtones blue, negative values tint midtones yellow.
• B Shadows : Positive values tint shadows blue, negative values tint shadows yellow.

Don't let the number of parameters scare you, it's simpler than it looks and it's very versatile.

Parameters:

• Seed : Seed number. Different seed values generate different noise patterns.
• Opacity : Noise opacity.
• Refresh : Refresh rate in frames for animated noise: x frames = new pattern . A value of 0 set it to static.
• Red value of noise color (0-255).
• Green value of noise color (0-255).
• Blue value of noise color (0-255).

The noise is not as random as I wish. I may improve the algorithm in the future.

Adjust Hue, Saturation and Value.

Parameters:

• Hue : Hue shift in degrees (180 = opposite hues). Accept negative values.
• Saturation : Color saturation percentage. Values bigger than 100% oversaturate colors.
• Value : Value percentage. Adjust the "lightness".

I made a pixelated noise effect that allows to set the color of the noise. Coincidently I was planning to release it this week, but delayed after the forum/site redesign. You can give a look at it, I will post it soon.

just an idea: make a tutorial about how to write a good tutorial, with good practices and etc, and lock it at the top if possible.

Nice integration between the forum and website!

Some impressions/suggestions:

-the text font (specially in the forums) seems too big and get a little uncomfortable to read;

-the page's content container seems a bit too narrow. As the most common resolution nowadays is 1024x768 or higher, I think it could be at least 900px wide to optimize screen space;

-if implemented the above suggestion I recommend enlarging a bit the lateral padding area as well to let the content breathe a little more;

-in the topics table would be nice to give odd rows a slightly distinct color to improve readability and association among the information on other columns;

-it would be nice to slice big tutorials into multiple pages. Maybe a system similar to instructables.com where you can separate into steps, visualize them individually or all at the same time.

This is more a matter of personal taste, but I particularly don't like the two tones of green together as to me they give a too eco-business identity. I think a gray would suit better instead of the dark green, and also be more techy.

Although I think would be even better if the header called a little more attention to it:

Use them as you wish.

The new system with folders seems a nice addition to C2.

It would be nice if you also had the option to select animations from a list rather than remembering their name and typing them every time in the events. If you don't need to use expressions to pick an animation it can get pretty annoying.

Another suggestion to the new animation system would be to better integrate it with the picture editor. It would be a lot more productive if you could add, delete, move frames, set speed, loop and preview straight from the picture editor. In my opinion, the Animator tab could be completely removed, then the Project tab would be used instead if you need to organize animations folders.

Well, you can fake it by changing the scale of the objects based on the Z position, so all the objects disappear (have scale 0) at the maximum allowed clipping depth, this decreases Z positioning resolution though.

example (based on chrisbrobs .cap):

http://dl.dropbox.com/u/7871870/construct/3d-scale.cap

Edit: Ok, I realized that the distance between objects were getting messed up when you only scale them, so I also applied the scale to the positions in order to fix it. Link above is updated with these changes.

I think he is asking about something that in 3D apps is called the "clipping distance"- the distance range away from the camera location in which objects are rendered or not, so they are clipped if too close or too far from the camera.

As far as I know construct doesn't have any option to specify that distance.

Thanks for the help guys!

I don't know much about python, even less about using external libraries, but I will try to figure it out. It can be an opportunity to learn something about python. I found some tutorials on the forum about the subject and will give it a try.

Anyhow, if someone also sympathizes with the cause and is capable of writing a plugin to set/get parallel port pins state will be highly welcome as well.
