我在這裏設置了一個主類,它從ArrayList呈現塊,但是我只看到最後一個被渲染。爲什麼我只能看到ArrayList中的最後一個塊?LWJGL 3D渲染不起作用
這是我渲染我的塊在我的主類:
glPushMatrix();
glTranslatef(0, 0, -10);
Brick.bind();
glBegin(GL_QUADS);
Block b;
for(int i = 0; i < blocks.size(); i++)
{
b = blocks.get(i);
b.render();
}
glEnd();
glPopMatrix(); Display.update();
這是我生成我塊:
public static void generateMap()
{
Block b;
for(float i = 0; i < 99; i += 3)
{
for(float r = 0; r < 99; r += 3)
{
b = new Block(i, 0f, r, 3f, 3f, 3f);
blocks.add(b);
}
}
}
然後,我有我做每塊時,此塊類:
import static org.lwjgl.opengl.GL11.glTexCoord2f;
import static org.lwjgl.opengl.GL11.glVertex3f;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;

import java.util.logging.Logger;

public class Block
{
protected static float x;
protected static float y;
protected static float z;
protected static float sx;
protected static float sy;
protected static float sz;
public Block(float x, float y, float z, float sx, float sy, float sz)
{
this.x = x;
this.y = y;
this.z = z;
this.sx = sx;
this.sy = sy;
this.sz = sz;
}
public static void render()
{
glTexCoord2f(0,0); glVertex3f(x-sx,y,z-sz);
glTexCoord2f(0,1); glVertex3f(x,y,z-sz);
glTexCoord2f(1,1); glVertex3f(x,y,z);
glTexCoord2f(1,0); glVertex3f(x-sx,y,z);

glTexCoord2f(0,0); glVertex3f(x-sx,y-sy,z-sz);

glTexCoord2f(1,0); glVertex3f(x-sx,y-sy,z);

glTexCoord2f(0,1); glVertex3f(x,y-sy,z-sz);

glTexCoord2f(1,0); glVertex3f(x-sx,y,z-sz);
//Left
glTexCoord2f(0,0); glVertex3f(x-sx,y,z);

glTexCoord2f(1,0); glVertex3f(x-sx,y,z-sz);
//Right
glTexCoord2f(0,0); glVertex3f(x,y,z);
glTexCoord2f(0,1); glVertex3f(x,y-sy,z);
glTexCoord2f(1,1); glVertex3f(x,y-sy,z-sz);
glTexCoord2f(1,0); glVertex3f(x,y,z-sz);
}
}
