Color change depending on health

[Poltergeist Azarov]

Hello, I am making a combat meter and wanted its color of floating text to be changed depending on health ratio. There gonna be three main colors as green, yellow and red. As much as agent's energy gets low floating text color needs to be changed. I tried some ways to do and failed to code something compact for this operation. Any ideas?

 

Edit: since colors are gonna be used depending on health ratio, color might seen as orange sometimes when agent's health is about %30. I failed coding it this perfect way.

In Psuedocode:-

floating_text = "Floating text"health = HealthyIf health = Healthy then     SetText(floating_text,<0,0,1>) //Green textElse If health = Sickly then     SetText(floating_text,<1,1,0>) //Yellow textElse     SetText(floating_text,<1,0,0>) //Red text
End If

 Remember that in SL, colours are set as <Red, Green, Blue> in vector form. Therefore:-

Green = <0,1,0>Yellow = <1,1,0>Orange = <1,0.5,0>Red = <1,0,0>

You don't need to use the 0-1 range for colours, can also use 0-255.

You can try this formula:

vector color_dead = <1,0,0>;    // color for nearly deadvector color_healthy = <0,1,0>;	// color for 100% healthfloat  health_level;            // 0-100......	vector color_level = (color_healthy - color_dead) * (health_level/100.0) + color_dead;......

 The color will float between color_dead (0%) and color_healthy (100%)

It's a linear interpolation. If you dont like the colors, nothing stops you from enhancing it and set a 50% color for example.

I was trying to code something that can slightly change the color instead of changing at each %30 decrease of the health. For example this code below changes given color to black slighty:

integer FTC=0;Uncolorize(vector color) {    integer x;    float CX=color.x; float CY=color.y; float CZ=color.z;    for (x=1; x<=10; ++x) {        if (CX>0.0) { CX-=0.1; }        if (CY>0.0) { CY-=0.1; }        if (CZ>0.0) { CZ-=0.1; }        llSetLinkPrimitiveParamsFast(3,[PRIM_COLOR, FTC, <CX,CY,CZ>, 0.99]);        llSleep(0.022);    }}

 Another example of a slight color change to given color:

Colorize(vector color) {    vector NewColorVar=<1.0, 1.0, 0.0>;    vector red=    <1.0, 0.0, 0.0>;    vector green=  <0.0, 1.0, 0.0>;    vector cyan=   <0.0, 1.0, 1.0>;    vector yellow= <1.0, 1.0, 0.0>;        integer x;     for (x=1; x<=10; ++x) {        if (color==red)   { NewColorVar+=<0.0,-0.1,0.0>; }        if (color==green) { NewColorVar+=<-0.1,0.0,0.0>; }        if (color==cyan)  { NewColorVar+=<-0.1,0.0,0.1>; }        llSetLinkPrimitiveParamsFast(3,[PRIM_COLOR, FTC, NewColorVar, 0.99]);        llSleep(0.022);    }}

I've coded these both but now I am really stuck at changing between three colors slightly.

Thanks alot nova, that seems to be what I was looking for.

Played alot with it and sadly failed to change between three colors :\ do you have a suggestion for that

I'm sure there are plenty of open source scripts that do this, but I'm too lazy to look for one now.

For values of health scaled to the range 0.0 to 1.0, you can probably get by using a color vector of simply

<1.0-health, health, 0.0> * 2.0

because a color is automatically range-constrained to no more than 1.0 for R, G, and B. That will however stick more in the mid-range of yellow than a more "accurate"

<1.0-health, health, 0.0> * (2.0 - 2.0*llFabs(0.5-health))

which scales the RGB dimensions into 1.0 ranges.

I have no idea what other scripts do. Maybe they're more clever.

For 3 colors it's the same, you just split it into a 0-50 and a 50-100 range

vector color_dead = <1,0,0>;    // color for nearly deadvector color_50 = <1,1,0>;vector color_healthy = <0,1,0>;	// color for 100% healthfloat  health_level;            // 0-100......	vector color_level;	if (health_level<50.0) color_level = (color_50 - color_dead) * (health_level/100.0) + color_dead;	                  else color_level = (color_healthy - color_50) * (health_level/100.0) + color_50;......

if you would like red orange green then

 

default{    state_entry()    {             float health = 0.5;  // health in range 0.0 .. 1.0                                 // blend health: 0.0 = red, 0.5 = orange, green = 1.0               vector blend = <2.0 - health * 2.0, health * 0.9, 0.0>;              llSetColor(blend, ALL_SIDES);    }}

Thank you all, these all are great.
