java - Errors with shininess -

i working on minecraft mod, , attempting create gun gold when specific person logged on. have worked out, except shininess itself. used code this site ambient, specular, diffuse , shininess of gold, when run game, error:

gl11.glmaterialf(gl11.gl_front, gl11.gl_ambient, 0.24725f); gl11.glmaterialf(gl11.gl_front, gl11.gl_diffuse, 0.75164f); gl11.glmaterialf(gl11.gl_front, gl11.gl_specular, 0.628281f); gl11.glmaterialf(gl11.gl_front, gl11.gl_shininess, 0.4f);

i copied code site, did not sense using shader, tried writing out opengl code (as can see above). however, when gun renders, colours gold (because write color code), not shine, , error printed console:

2014-06-21 18:27:36 [severe] [minecraft-client] ########## gl error ########## 2014-06-21 18:27:36 [severe] [minecraft-client] @ post render 2014-06-21 18:27:36 [severe] [minecraft-client] 1280: invalid enum

does have ideas? isn't question minecraft modding, more opengl rendering.

(btw, rendering lwjgl , java 6)

the error occurs because gl_ambient, gl_diffuse , gl_specular not valid arguments glmaterialf(). define rgba vectors of material coefficients, not single scalar value seek set. have utilize glmaterialfv() instead , specify 4 components per parameter. table linked maks clear having 3 values (rgb) per parameter, ignor alpha component, isn't relevent material itself, still have specify one.

but have warn result still not realistic unless reflection technics used, environment mapping.
