Java Programming: Let's Build a Zombie Game #4

in this tutorial we develop a shooting system into the game! Here is the code for the angles...

int bulletVelocity = 10;

Have fun learning!

Nice to see you back man, I get nostalgia even watching your modern tuts.

Running into an error, the line
GameObject tempBullet = handler.addObject(new Bullet(tempPlayer.x+16, tempPlayer.y+16, ID.Bullet));


is giving the error "incompatible types:void cannot be converted to GameObject"


Everything has run smooth up until this.

the error you receive at 10:18 can be fixed by using the CopyOnWriteArrayList Collection, its a thread save ArrayList where objects can be added and deleted during the loop

Finally you're back! Waiting for more videos :))))

Hello my friend, thank you always so much for your videos, it really help me, can you upload someday a video explaining how to create a pathfinding for platform games please? I will thank you so much

On 7:48 I can only move Diagonoly
Can you please tell me what the problem is.
Thank You

Great video! may I ask why choose to develop a game in plain java rather than with game engine like unity?

[ahinssu]

Can you please help me my Bullet doesnt work

[martaprat]

i'm getting a error Require: GameObject Found: void
GameObject tempBullet = handler.addObject(new Bullet(tempPlayer.x + 16, tempPlayer.y + 16, ID.Bullet))
how can i fix this

[dangerkid]

for me my bullets aren't spawning
here is what I have in my file:

import java.awt.Color;
import java.awt.Graphics;
public class Bullet extends GameObject{
public Bullet(float x, float y, ID id) {
super(x, y, id);
}
@Override
public void tick() {
x += velX;
y += velY;
}
@Override
public void render(Graphics g) {
g.setColor(Color.yellow);
g.fillRect((int)x, (int)y, 10, 10);
}
}

Keep getting a crash when clicking in the game and its about this line:


if(tempPlayer != null) {
GameObject tempBullet = handler.addObject(new Bullet(tempPlayer.x+16, tempPlayer.y+16, ID.Bullet));
}else findPLayer();


in this line of code it gives an error and it says I need to change the return type for addObject to GameObject instead of void in this line:


public void addObject(GameObject tempObject) {
object.add(tempObject);


but doing that gives me another crash...

Will "So much blood" will be updated in like ever or do you count is as a completed project? Because in my opinion you DID pour care into it but just that is not enough, you also need to pour it into the right things and the right amount. Then again it was like 3 years ago so you might have just forgotten about all that stuff.

Hope u will end this tutorial! it looks great so far!

[fssimply]
