I am trying to set a rule using a boolean expression that when X is within a range (6.0 -8.0) then yellow, anything below is green and above red. Your help is greatly appreciated
You mean like this?
if(X<6) {
color=green;
}
else {
if(x<=8){
color=yellow;
}else{
color=red;
}
}
You can accomplish this with simple if statements (exact syntax will vary by language, of course):
if X < 6.0 then
color = green
else if X <= 8.0 then
color = yellow
else
color = red
end

I'm new in a flutter. I can't figure out how to generate the 2 random colours on the same Text(). Can anyone help me out? Really appreciate.
String data = "+RM67.80";
var value = data.substring(0,1); // it will get the first character
After that you can check the condition if value == "+" apply green color otherwise apply red.
I have this mini task in my game where you need to click trophies to change color of the wood on them. I have two arrays of colors, one is an array containing all possible colors and the other one contains four colors (the answer) as follows:
I've double checked that the colors are equal between the two arrays. For example the purple in Colors-array has exactly the same r, g, b & a values as the purple in the Right Order-array.
To check whether the trophies has correct color I just loop through them and grab their material color. Then I check that color against the Right Order-array but it's not quite working. For example when my first trophy is purple it should be correct, but it's not because for some reason Unity is returning slightly different material color than excepted:
Hope somebody knows why this is happening.
When you say, they are exactly same color, I assume you are referring rgb values from Color Inspector, which are not precise values.
Now I dont know what could be causing in different values of colors but
You can write an extension method to compare the values after rounding them to closest integer.
public static class Extensions
{
public static bool CompareRGB(this Color thisColor, Color otherColor)
{
return
Mathf.RoundToInt(thisColor.r * 255) == Mathf.RoundToInt(otherColor.r * 255) &&
Mathf.RoundToInt(thisColor.b * 255) == Mathf.RoundToInt(otherColor.b * 255) &&
Mathf.RoundToInt(thisColor.g * 255) == Mathf.RoundToInt(otherColor.g * 255);
}
}
usage:
Color red = Color.Red;
red.CompareRGB(Color.Red); // true;
red.CompareRGB(Color.Green); // false;
Hope this helps.
I would use a palette. This is simply an array of all the possible colors you use (sounds like you have this). Record, for each "trophy", the INDEX into this array, at the same time you assign the color to the renderer. Also, record the index for each "button", at the same time you assign the color to the renderer.
Then you can simply compare the palette index values (simple integers) to see if the color matches.
I have a crystal report field with name 'Comp' which will contain the text 'correct' or 'not correct' according to some formula. what i want to achieve is, if text is correct i want to make it green color, otherwise red.
Got it after some search, here is the answer
if{Comp} = "correct" then crGreen else crRed
you can create formula in your program too:
FormulaFieldDefinitions definitions = MyReport.FormulaFields;
string formulaText = "IF " + MyReport.Database.Tables[1].Fields[1].Name
+ " = correct THEN crGreen else crRed";
definitions.Add("Test", formulaText);
MyReport.Sections[1].AddFieldObject(definitions[1], 0, 0);
I am not sure if this is possible as I have been looking for a few hours and cant find what I am looking for.
What i am doing is taking a color from a game panel which is semi translucent so the color which I am taking is always subtly changing. What is need is a way to check if it is +/- 10 or so shades of my desired color.
Something like
If color1 is +/-10 of 0x?
I have tried using the image search to do similar but that didn't work.
Any help would be greatly appreciated
In addition to Robert's answer, you can compare the colors mathematically.
First start by separating the Red, Green, and Blue values.
ToRGB(color) {
return { "r": (color >> 16) & 0xFF, "g": (color >> 8) & 0xFF, "b": color & 0xFF }
}
Then we need a function that compares the colors. Each of thee variables holds a number representing the difference in the two color values. For example if red is 255 in c1, and 200 in c2, rdiff will be 55. We use Abs so that we don't end up with -55 when c2 has a higher value. Then we make sure the difference for each of these is less than our vary.
Compare(c1, c2, vary=20) {
rdiff := Abs( c1.r - c2.r )
gdiff := Abs( c1.g - c2.g )
bdiff := Abs( c1.b - c2.b )
return rdiff <= vary && gdiff <= vary && bdiff <= vary
}
Here's how it can be used. We take some numbers, and then compare them to each other with the default vary of 20.
light_pink := ToRGB(0xFFAAFF)
darker_pink := ToRGB(0xFAACEF)
purple := ToRGB(0xAA00FF)
MsgBox % Compare(light_pink, dark_pink) ; True
MsgBox % Compare(light_pink, purple) ; False
I assume that your read about the limitations of PixelGetColor: Known limitations:
"A window that is partially transparent or that has one of its colors marked invisible (TransColor) typically yields colors for the window behind itself rather than its own.
PixelGetColor might not produce accurate results for certain applications. If this occurs, try specifying the word Alt or Slow in the last parameter."
When using ImageSearch, you can specify the Delta of the colours. Example:
ImageSearch, FoundX, FoundY, %SearchRangeLeft%, %SearchRangeTop%, %SearchRangeRight%, %SearchRangeBottom%, *20 %ImageFile%
Here the *20 indicates the variation in the range from 0 to 255 of my search colour. When searching for a pixel inside the image of 100,100,100 (RGB), it will match anything between 80,80,80 and 120,120,120. Hope this helps, but matching transparent colours is difficult and prone to errors. The smaller the image and search range the better (and faster)
For a game that I am currently making, I have a black background with many white dots, which are being used to represent stars. I have no need for the black color however, and I only wish for the stars to show. My question is this: Is it possible to completely hide the black color without using an image manipulation program, that is, using only code? Any help is appreciated.
This is the form:
// some rgba color representation
struct t_rgba {
uint8_t r, g, b, a;
};
bool SetToTransparentIfPixelIsBlack(t_rgba* const rgba) {
// is it black?
if (0 == rgba->r && 0 == rgba->g && 0 == rgba->b) {
// then set the alpha value to transparent:
rgba->a = 0;
}
}
although the image data you are using will be represented differently.
