Hello and I'm trying to make my own game engine in Java. I have completed all the necessary ones but I can't figure it out with the TileGame class. It just can't scroll. Also there are no exceptions. Here I'm listing the code.
TileGame.java
@Override
public void draw(Graphics2D g) {
if (back!=null){
back.render(g);
}
if (follower!=null){
follower.render(g);
follower.draw(g);
}
for (int i=0; i<actors.size(); i++){
Actor actor = actors.get(i);
if (actor!=follower&&getVisibleRect().intersects(actor.getBounds())){
g.drawImage(actor.getAnimation().getFrameImage(), actor.x - OffSetX, actor.y - OffSetY, null);
actor.draw(g);
}
}
}
/**
* This method returns the visible rectangle
* @return The visible rectangle
*/
public Rectangle getVisibleRect(){
return new Rectangle(OffSetX, OffSetY, global.WIDTH, global.HEIGHT);
}
@Override
public void update(){
if (follower!=null){
if (scrollHorizontally){
OffSetX = global.WIDTH/2 -
Math.round((float)follower.x) - tileSize;
OffSetX =
Math.min(OffSetX, 0);
OffSetX =
Math.max(OffSetX, global.WIDTH - mapWidth);
}
if (scrollVertically){
OffSetY = global.HEIGHT/2 -
Math.round((float)follower.y) - tileSize;
OffSetY =
Math.min(OffSetY, 0);
OffSetY =
Math.max(OffSetY, global.HEIGHT - mapHeight);
}
}
for (int i=0; i<actors.size(); i++){
Actor actor1 = actors.get(i);
if (getVisibleRect().contains(actor1.x, actor1.y)){
actor1.update();
for (int j=0; j<actors.size(); j++){
Actor actor2 = actors.get(j);
if (actor1.isCollidingWith(actor2)){
actor1.collision(actor2);
actor2.collision(actor1);
}
}
}
}
}
but the problem is that all the actors are working, but it just won't scroll. Help Please.. Thanks in Advance.
