8:09 ?? generateLevel() method... which episode did we write that code?? Mine is empty...

As much as I appreciate the return of Game Programming, I really would like to see Network Chat Programming continue since it likely only has a few more episodes to go.

Hi, i need a little help, my projectile doesn't dissapear propertly, it dissapears to the left side, but kinda wrong on the right, the system does not calculate it, but i can see it, only to the right side, how that someone understanded me, thanks.

When I run my code nothing shows up in the console and there is no JFrame I don't know were i went wrong any ideas.

[footballerrm]

Are we going to start on Multiplayer and chatbox and stuff after particles?

[CompletAfon]

can i use this programming courses in my android java codes ?

[HeyItsUltra]

I prefer to keep all entities in the entities list, but still add particles to projectiles and such. That way I don't need to worry about cycling through multiple lists, but things are still organized.

[Chargon]

can we do particle effect with this ? Cirlce, star ect... because i can't figure it out..

[SamBrev]

can i also say that in your level.update() method you could do for(Entity e : entities) instead of for(int i = 0; i < entities.size(); i++) because it looks cleaner and is easier to read and comprehend

What do you think about making an object-c tutorial?
I'd love to learn how to programm iOS apps

[SpectraPrime]

Love the series, just a minor observation, is it not more logical to use a switch statement instead of a large string of if, else if, else? where you're essentially checking the same thing for multiple different values?

[billybobism]

I think a spawner object isn't a good idea, I think you should make it a method in level because the object does only one thing like a method. This then means you don't have random objects that never get used again. Also it seems pointless to use the enum. You should pass in an example entity of what you want to spawn which you can then get the things like life and other details about the entity you want to spawn.

[TheCherno]

Objective-C's syntax gives me nightmares.

[daniellionel]

i think you could also make the init-function returning this entity so you can write level.add(new Spawner(x, y, amount).init(this))

[RsTheZigec]

How I would handle the problem with the level is probably spawning new Particles from the init method. I would just call super.init() and then spawn new particles.

[TheLiquidPepper]

The code in this video code differs from mine, which is copied from previous videos. Where you use a variable "projectiles" I have a function getProjectiles(). E.g. "projectiles.size()" is for me "getProjectiles().size()".

[CoryCothrum]

Can you put this on github, like the chat program?

[TheEggHealer]

Thank you for another great tutorial! :) YOU'RE AWESOME

[Brakleet]

Another nice episode dude! Wen i become rich from my video game i am gonna share half with you for teaching me!

[dimi]

You'll fall in love with the syntax after a while ;)
