LWJGL GLTranslation add to previos Translation
i've got a problem with coding here. When i render 2 ore more blocks the location with the new block add with the old ones and so there's different distances between theese blocks. I used a FPCameraController and so I cannot add GL11.glloadIdentify() because my blocks disappears.
Rendering Class:
while(!Display.isCloseRequested) { GL11.glClear(GL11.GL_COLOR_BUFFER_BIT | GL11.GL_DEPTH_BUFFER_BIT | GL11.GL_STENCIL_BUFFER_BIT);
GL11.glCullFace(GL11.GL_BACK);
GL11.glEnable(GL11.GL_CULL_FACE);
GL11.glEnable(GL11.GL_DEPTH_TEST);
GL11.glDisable(GL11.GL_BLEND);
GL11.glPopMatrix(); //From 2D
GL11.glMatrixMode(GL11.GL_PROJECTION);
GL11.glLoadIdentity();
GLU.gluPerspective(45f, (float) Display.getWidth() / Display.getHeight(), 0.1f, 1000);
GL11.glViewport(0, 0, Display.getWidth(), Display.getHeight());
GL11.glMatrixMode(GL11.GL_MODELVIEW);
//distance in mouse movement from the last getDX() call.
dx = Mouse.getDX();
//distance in mouse movement from the last getDY() call.
dy = Mouse.getDY();
//controll camera yaw from x movement fromt the mouse
camera.yaw(dx * mouseSensitivity);
//controll camera pitch from y movement fromt the mouse
camera.pitch(dy * mouseSensitivity);
//when passing in the distance to move
//we times the movementSpeed with dt this is a time scale
//so if its a slow frame u move more then a fast frame
//so on a slow computer you move just as fast as on a fast computer
if (Keyboard.isKeyDown(Keyboard.KEY_W))//move forward
{
camera.walkForward(movementSpeed*dt);
}
if (Keyboard.isKeyDown(Keyboard.KEY_S))//move backwards
{
camera.walkBackwards(movementSpeed*dt);
}
if (Keyboard.isKeyDown(Keyboard.KEY_A))//strafe left
{
camera.strafeLeft(movementSpeed*dt);
}
if (Keyboard.isKeyDown(Keyboard.KEY_D))//strafe right
{
camera.strafeRight(movementSpeed*dt);
}
CubeRenderer.renderTexturedCube(TextureManager.cube_unknown.getTexture(), 0,0,0);
CubeRenderer.renderTexturedCube(TextureManager.cube_unknown.getTexture(), 0,1,0);
CubeRenderer.renderTexturedCube(TextureManager.cube_unknown.getTexture(), 0,2,0);
CubeRenderer.renderTexturedCube(TextureManager.cube_unknown.getTexture(), 1,2,0);
CubeRenderer.renderTexturedCube(TextureManager.cube_unknown.getTexture(), -1,2,0);

camera.lookThrough();

Display.destroy();

Use GL11.glPushMatrix to save the old matrix and GL11.glPopMatrix to restore it. In renderTexturedCube (or wherever you want):
GL11.glPushMatrix(); // saves the current matrix
GL11.glTranslatef(x, y, z);
GL11.glRotatef(0, 0.0f, 0.0f, 0.0f); // not sure why you have this; it does nothing
// rest of cube rendering code goes here
GL11.glPopMatrix(); // restore the matrix that was saved at the start of the method
