//-----------------------------------------------------------

//Set a category to use from your .lang file (leave blank if you wish to use a literal string)
ImGui_SetTransCategory("Messages");
//category (String)- the name of the category you wish to read from. Should match the category name you are using in your .lang file.

//Create label data variable
cImGuiLabelData label;

//Returns a vector with a screen position (calculates the position on the screen fiven only a value between 0 and 1)
ImGui_NrmPos(0,0,10.0)
//xPosNormalized (float)- the normalized x position (between 0 and 1). Ex. 0.5 will be the center of the x axis.
//yPosNormalized (float)- the normalized y position (between 0 and 1). Ex. 0.5 will be the center of the y axis.
//zPosNormalized (float)- the normalized z position (between 0 and 1). Note: Not used when printing text on screen.

//Returns a vector with the size in screen to work on (1,1 for whole screen)
ImGui_NrmSize(1.0f,1.0f)
//xSizeNormalized (float)- the normalized x size (between 0 and 1). Ex. 0.5 will be half the x zxis.
//ySizeNormalized (float)- the normalized y size (between 0 and 1). Ex. 0.5 will be half the y axis.

//Print a label on the players GUI
ImGui_DoLabelExt("Message_1", label, ImGui_NrmPos(0,0,10.0), ImGui_NrmSize(1.0f,1.0f));
//entryName (String)- the entry name that contains the text you wish to print (from the .lang file). If TransCategory is "" then it will print out whatever String is written here.
//labelData (cImGuiLabelData)- the label data variable that stores all your text format data.
//screenPosition (cVector3f)- a 3D vector that indicates the x, y, z screen position of where the text should be placed.
//screenSpaceSize (cVector2f)- a 2D vector that indicates the x, y in screen size. (Use 1.0, 1.0 for whole screen)

//The OnGui function
void OnGui(float afTimeStep)
{

}

//Global variable showMessage that stores whether or not we want to show our message
bool showMessage = false;

//Put an if inside the OnGui function with our boolean variable
if(showMessage){

}

//Specify how you want your text alligned (use eFontAlign_ to find a position)
label.mFontAlign = eFontAlign_Center;

//Specify the x,y size of the font in a vector2f format
label.mFont.mvSize = cVector2f(50,50);

//Change color of text to a preset one using cColor_
label.mColorBase = cColor_Red;

//Change color of text to specific color
//Check color wheel color https://www.colorspire.com/
//Normalize the RGB colors by dividing by 255
label.mColorBase = cColor(.501, 0, 1.0);

//Change the transparency of the text (a float from 0 to 1, 0 = 0% visible and 1 = 100% visible)
label.mColorBase.a = 1.0f;

//Total time message will be on screen fading in and out (2.5 seconds fading in and 2.5 fading out while using a linear easing function)
float messageFadeInAndOutTime = 5.0f;

//Create an oscillator that return the color and transparancy of a color to another color and then change it back repeatedly
ImGui_FadeOscillateColor("label", cColor(1, 1, 1, 0), cColor(1, 1, 1, 1), messageFadeInAndOutTime, eEasing_Linear);
//oscillatorName (String)- the name of the osillator which you can call later in your code.
//startColor (cColor)- the color and transparancy to start the oscillator at. cColor(R, G, B, a).
//goalColor (cColor)- the color and transparancy to reach. cColor(R, G, B, a).
//oscillationTime (float)- the total time it should take for the ossilator to make one full cycle (From A to B and back to A).
//easingFunction (eEasing)- the function that should be used to get from color A to color B and back. (Use eEasing_Linear for basic usage)

//Set the transparency of the text using a color oscillator
label.mColorBase.a = ImGui_FadeOscillateColor("label", cColor(1, 1, 1, 0), cColor(1, 1, 1, 1), messageFadeInAndOutTime, eEasing_Linear).a;

//If statement to disable message when fade is done
if(label.mColorBase.a == 0) showMessage = false;
