java - LWJGL - not all display lists rendering -


i'm working on minecraft game. create display list each 16x16x16 chunk. works fine. when i'm trying add block selection it's invisible. appears when i'm @ random positions(i render selection @ 0, 0, 0) . have no idea wrong.

my render loop:

while (isrunning) {     glclear(gl_color_buffer_bit | gl_depth_buffer_bit);      timer.nextframe();     input(timer.getdelta());      tex.bind();     glloadidentity();      renderchunks();      rendertext();     renderselection();      display.update();     errorcheck();     if (display.iscloserequested()) {         isrunning = false;     } }

renderchunks:

glrotated(player.getry(), 1, 0, 0); glrotated(player.getrx(), 0, 1, 0); gltranslatef(-player.getx(), -player.gety(), -player.getz()); //--------- (int x = minworldchunkx; x < maxworldchunkx; ++x) {     (int y = minworldchunky; y < maxworldchunky; ++y) {         (int z = minworldchunkz; z < maxworldchunkz; ++z) {         glpushmatrix();         gltranslatef(x << 4, y << 4, z << 4);         glcalllist(chunkdisplaylists.get(new chunkposition(x, y, z)));         glpopmatrix();         }     } }

renderselection:

glpushmatrix(); glcalllist(selectiondisplaylist); glpopmatrix();

selection display list:

selectiondisplaylist = glgenlists(1); glnewlist(selectiondisplaylist, gl_compile); glbegin(gl_lines); glcolor3f(0, 0, 0); gllinewidth(3);  glvertex3f(1, 1, 1); glvertex3f(1, 0, 1);  glvertex3f(1, 0, 1); glvertex3f(1, 0, 0);  glvertex3f(1, 0, 0); glvertex3f(1, 1, 0);  glvertex3f(1, 1, 0); glvertex3f(1, 1, 1);    glvertex3f(0, 1, 0); glvertex3f(0, 0, 0);  glvertex3f(0, 0, 0); glvertex3f(0, 0, 1);  glvertex3f(0, 0, 1); glvertex3f(0, 1, 1);  glvertex3f(0, 1, 1); glvertex3f(0, 1, 0);   glvertex3f(0, 1, 0); glvertex3f(1, 1, 0);  glvertex3f(0, 0, 0); glvertex3f(1, 0, 0);  glvertex3f(0, 0, 1); glvertex3f(1, 0, 1);  glvertex3f(0, 1, 1); glvertex3f(1, 1, 1); glend(); glendlist();

source code avaible on github

edit: when moved renderselection() render loop renderchunks() before rendering chunks worked. when change renderselection() to:

glpushmatrix(); gldisable(gl_depth_test); glcalllist(selectiondisplaylist); glenable(gl_depth_test); glpopmatrix();

it disappears completely.

edit 2: disabling blending while rendering selection fixed it.

screenshos

disabling blending while rendering block selection fixed it.

new renderselection code:

glpushmatrix(); gldisable(gl_depth_test); gldisable(gl_blend); glcalllist(selectiondisplaylist); glenable(gl_depth_test); glenable(gl_blend); glpopmatrix();

update: wan caused else:

selectiondisplaylist = glgenlists(1); glnewlist(selectiondisplaylist, gl_compile); glbegin(gl_lines); ... gllinewidth(3);//this caused issue ...

normally setting line width between glbegin() , glend() should cause error, did not on computer (ati graphics card, ubuntu). on other computer glerror() returned non-zero value.

SPSS keyboard combination alters encoding -

my question not have programming practical issue on spss. accident keyword combination cannot remember because did not intend press changed encoding in spss , text in data in different language english shown small boxes. nevertheless, when kind of analysis performed different language text shown in output. does know reason? tried change encoding did not produce result. first, @ edit > options , see whether setting unicode or locale. might fix it. if have text in multiple languages, want unicode. otherwise, may have specific locale set wrong. can change set locale, need know locale want use.
