java - Drawing text to display -


i'm trying draw text screen in lwjgl following this tutorial. problem when ever draw text screen, draws but when draw quad with text, quad not show.

game class

package moa.bermudez;  import static org.lwjgl.opengl.gl11.*;  import java.awt.font; import java.io.inputstream;  import moa.bermudez.utils.artist;  import org.lwjgl.lwjglexception; import org.lwjgl.opengl.display; import org.lwjgl.opengl.displaymode; import org.newdawn.slick.truetypefont;  public class game  { public static final int width = 320; public static final int height = width * 9 / 16; public static final int scale = 3; public static final string name = "----"; public static final float version = 0.1f; public static final int max_fps = 60;  private truetypefont font; private boolean fontas = true;  public game()  {     try      {         display.setdisplaymode(new displaymode(width * scale, height * scale));         display.settitle(name + " " + version);         display.create();     } catch(lwjglexception e)     {         e.printstacktrace();         display.destroy();     }      init();     while(!display.iscloserequested())     {         setcamera();         update();         display.sync(max_fps);     }      display.destroy(); }  public void update() {            glclear(gl_color_buffer_bit);      font.drawstring(0, 0, "this text showing");     artist.drawquad(0, 0, 100, 100);    // not showing.      display.update(); }  public void setcamera() {     glmatrixmode(gl_projection);     glloadidentity();     glviewport(0, 0, width * scale, height * scale);     glortho(0, width * scale, height * scale, 0, 1, -1);     glmatrixmode(gl_modelview);     glenable(gl_texture_2d);     glenable(gl_blend);     glblendfunc(gl_src_alpha, gl_one_minus_src_alpha); }  public void init() {     try {         inputstream inputstream = moa.bermudez.fonts.font.default_font;          font awtfont = font.createfont(font.truetype_font, inputstream);         awtfont = awtfont.derivefont(24f);          font = new truetypefont(awtfont, fontas);     } catch (exception e) {         e.printstacktrace();     } }  public static void main(string[] args) {     new game(); } }

artist's drawquad method

public static void drawquad(float x, float y, float width, float height) {     glbegin(gl_quads);          glcolor3d(0, 0, 1);         glvertex2f(x, y);         glvertex2f(x + width, y);         glvertex2f(x + width, y + height);         glvertex2f(x, y + height);      glend(); }

after searching, found solution this stackoverflow post

not calling glenable(gl_blend) in initgl calling glenable(gl_blend) when draw text should make work.

glenable(gl_blend); font.drawstring(0, 0, "this text should appear"); gldisable(gl_blend);
