I am making a 3D game using LWJGL and I have a texture class with static variables so that I only need to load textures once, even if I need to use them more than once. I am using Slick Util for this. When I bind a texture it works fine, but then when I try to render something else after I have rendered the model with the texture, the texture is still being bound. How do I unbind the texture and set the rendermode to the one that was in use before any textures were bound? Some of my code is below. The problem I am having is the player texture is being used in the box drawn around the player after it the model has been rendered.
Model.java
public class Model {
public List<Vector3f> vertices = new ArrayList<Vector3f>();
public List<Vector3f> normals = new ArrayList<Vector3f>();
public ArrayList<Vector2f> textureCoords = new ArrayList<Vector2f>();
public List<Face> faces = new ArrayList<Face>();
public static Model TREE;
public static Model PLAYER;
public static void loadModels() {
try {
TREE = OBJLoader.loadModel(new File("assets/model/tree_pine_0.obj"));
PLAYER = OBJLoader.loadModel(new File("assets/model/player.obj"));
} catch (Exception e) {
e.printStackTrace();
}
}
public void render(Vector3f position, Vector3f scale, Vector3f rotation, Texture texture, float shinyness) {
glPushMatrix();
{
texture.bind();
glColor3f(1, 1, 1);
glTranslatef(position.x, position.y, position.z);
glScalef(scale.x, scale.y, scale.z);
glRotatef(rotation.x, 1, 0, 0);
glRotatef(rotation.y, 0, 1, 0);
glRotatef(rotation.z, 0, 0, 1);
glMaterialf(GL_FRONT, GL_SHININESS, shinyness);
glBegin(GL_TRIANGLES);
{
for (Face face : faces) {
Vector2f t1 = textureCoords.get((int) face.textureCoords.x - 1);
glTexCoord2f(t1.x, t1.y);
Vector3f n1 = normals.get((int) face.normal.x - 1);
glNormal3f(n1.x, n1.y, n1.z);
Vector3f v1 = vertices.get((int) face.vertex.x - 1);
glVertex3f(v1.x, v1.y, v1.z);
Vector2f t2 = textureCoords.get((int) face.textureCoords.y - 1);
glTexCoord2f(t2.x, t2.y);
Vector3f n2 = normals.get((int) face.normal.y - 1);
glNormal3f(n2.x, n2.y, n2.z);
Vector3f v2 = vertices.get((int) face.vertex.y - 1);
glVertex3f(v2.x, v2.y, v2.z);
Vector2f t3 = textureCoords.get((int) face.textureCoords.z - 1);

}
texture.release();
}
glEnd();
