LWJGL GLTranslation添加到previos翻译
我在这里编码时遇到了问题。 当我渲染2块或更多块时，新块的位置会与旧块一起添加，因此这些块之间的距离不同。 我使用了FPCameraController，所以我不能添加GL11.glloadIdentify（），因为我的块消失了。
渲染类：
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);
GL11.glLoadIdentity();
camera.lookThrough();
Display.sync(60);
Display.update();
}
Display.destroy();
用这些变量渲染类：Texture tex; float x，y，z;
GL11.glTranslatef（X，Y，Z）;
GL11.glRotatef（0,0.0f，0.0F，0.0F）;
GL11.glColor3f（0.5F，0.5F，1.0F）;
tex.bind（）; GL11.glPolygonMode（GL11.GL_FRONT，GL11.GL_FILL）;
GL11.glBegin(GL11.GL_QUADS);
GL11.glTexCoord2f(0, 0); GL11.glVertex3f(-1, -1, 1);
GL11.glTexCoord2f(0, 1); GL11.glVertex3f(1, -1, 1);
GL11.glTexCoord2f(1, 1); GL11.glVertex3f(1, 1, 1);
GL11.glTexCoord2f(1, 0); GL11.glVertex3f(-1, 1, 1);
GL11.glEnd();
//left
GL11.glBegin(GL11.GL_QUADS);
GL11.glTexCoord2f(0, 0); GL11.glVertex3f(-1, -1, -1);
GL11.glTexCoord2f(0, 1); GL11.glVertex3f(-1, -1, 1);
GL11.glTexCoord2f(1, 1); GL11.glVertex3f(-1, 1, 1);
GL11.glTexCoord2f(1, 0); GL11.glVertex3f(-1, 1, -1);
GL11.glEnd();
//right
GL11.glBegin(GL11.GL_QUADS);
GL11.glTexCoord2f(0, 0); GL11.glVertex3f(1, -1, -1);
GL11.glTexCoord2f(0, 1); GL11.glVertex3f(1, 1, -1);
GL11.glTexCoord2f(1, 1); GL11.glVertex3f(1, 1, 1);
GL11.glTexCoord2f(1, 0); GL11.glVertex3f(1, -1, 1);
GL11.glEnd();
//front
GL11.glBegin(GL11.GL_QUADS);
GL11.glTexCoord2f(0, 0); GL11.glVertex3f(-1, -1, -1);
GL11.glTexCoord2f(0, 1); GL11.glVertex3f(1, -1, -1);
GL11.glTexCoord2f(1, 1); GL11.glVertex3f(1, -1, 1);
GL11.glTexCoord2f(1, 0); GL11.glVertex3f(-1, -1, 1);
GL11.glEnd();
//back
GL11.glBegin(GL11.GL_QUADS);
GL11.glTexCoord2f(0, 0); GL11.glVertex3f(1, 1, -1);
GL11.glTexCoord2f(0, 1); GL11.glVertex3f(-1, 1, -1);
GL11.glTexCoord2f(1, 1); GL11.glVertex3f(-1, 1, 1);
GL11.glTexCoord2f(1, 0); GL11.glVertex3f(1, 1, 1);
GL11.glEnd();
//bottom
GL11.glBegin(GL11.GL_QUADS);
GL11.glTexCoord2f(0, 0); GL11.glVertex3f(1, -1, -1);
GL11.glTexCoord2f(0, 1); GL11.glVertex3f(-1, -1, -1);
GL11.glTexCoord2f(1, 1); GL11.glVertex3f(-1, 1, -1);
GL11.glTexCoord2f(1, 0); GL11.glVertex3f(1, 1, -1);
GL11.glEnd();
使用GL11.glPushMatrix来保存旧的矩阵和GL11.glPopMatrix以恢复它。 在renderTexturedCube （或任何你想要的）：
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
