TextEngine

Not everything (if any) which is written here will be in the final game!

An engine, that renders text on openGLTextures, and displays them on the screen.

usage

• simple:

  #include "text.h"
  ...
      // create a new Text.
      Text* newText = new Text("fontfile.ttf", 16);
      // set some color (red, green, blue [0-1])
      newText->setColor(1, 0, 0);
      // set some blending, and everything will shine through.
      newText->setBlending(.8);
      // set another alignment
      newText->setAlignment(TEXT_ALIGN_LEFT);
      // and display some text
      newText->setText("wow... so easy??");
  ...
  

• advanced:
  • Text implements Element2D from Render2D
  • you can reload fonts using

       newText->setFont(const char* fontFile, unsigned int fontSize);
    

  • if you like to be quick, and handle the char-array externally (the text wont delete the array, and will segfault, if the char-array is deleted) use something like: (notice the true)

       char* textPointerHandledExternally = "blabla";
       newText->setText(textPointerHandledExternally, true);
    

  • Hiding text:

       newText->setVisibility(false);
