Java Game Programming Episodes 6-10: Tiles & Levels

Welcome to Game Programming! In this series we go over how to make a video game from scratch using the programming language Java (same as Minecraft)! In Episode 6 to Episode 10 we spend time creating our TileGrids and Tiles which will serve as the map or battlefield for the game we're making.

Does anyone else get a problem at 5:26, when I type glEnable(GL_TEXTURE_2D); I get a red line under (GL_TEXTURE_2D) Did I forget to import something?
I followed the video as best I could, please help, anyone.
Thanks

At 18:43 my 2 textures don't go next to each other for some reason the grass goes on top of the dirt in the top left corner. I also have a little blue dot on the part which says when there's an error, which reads line breakpoint:boot [line 19] - boot(), next to the line Texture t2 = QuickLoad("Grass64"); I'm pretty sure I've followed everything correctly. Does anyone know why?

14:00 After typing "InputStream" and the whole load a red underline appears! Help!

@15:29 my DrawQuadTex has an error and the auto fix is create method "blah blah blah" and I have done command shift "o" MANY MANY MANY times. Plz help.

glEnable, glTranslate and glTexCoord2f are not defined methods for me, what can i do to fix this?

[kathleendahl]

Hello! Okay, I'm stuck at 3:42. The line that's giving me problems is "glOrtho(0, 1, WIDTH, HEIGHT, 0, 1, -1);
It says that the method glOrtho in the type GL11 is not applicable for the int arguments passed as HEIGHT and WIDTH. How do I fix that?

[nightcrabstudios]

hey, I need help, in my artist.java every glTranslatef and glTexCoord2f is an error. if it helps I'm at 11:30 in the video please help. thanks

Hey IP, at around 24:30 when you make the tile and then run it and all, it does nothing except immediately crash for me. Any ideas? I can provide the code if needed but I'm fairly certain I copied it all 100%...

Thanks.

[johnsmith]

Could someone please help mei have checked checked and rechecked my code over and over and for some reason after i set up the getters and setters when i run the program my tile flashes over and over super fast in the top left corner!

[thommathew]

I wrote everything like you did on your video, but my grass is white.. Why is that happening? Can find how to fix it.. :(

[thecheckeredcube]

youre the best java teacher on all youtube! keep up the good work!

[ayden]

I have a problem: When I typed "InputStream" it and everything associated with it did not work. Any help would be much appreciated. Thank you.

[yihao]

anyone with the "glEnable(GL_TEXTURE_2D);" not working just import "static org.lwjgl.opengl.GL11.*;"

Even though my quad is 64x64 and my texture is 64x64, the quad that is rendered to the screen does not look like a square... It is definitely much more rectangular. Do you know why?

[jamesisjamesable]

I keep getting 'The local variable t may not have been initialized', do i have to initialize every new local variable?
also every time I load a texture it makes me surround it with a try/catch, any idea why this might be happening?

[CaptainWardi]

I get this error
(Exception in thread "main" java.lang.Error: Unresolved compilation problem:
Type mismatch: cannot convert from java.io.InputStream to

[coreykuehl]

I added the glEnable(GL_TEXTURE_2D); and it gave me an error saying that it didn't recognize the variable GL_TEXTURE_2D. I then imported it and it is now saying that the method glEnable(int); is undefined for type Artist. Not sure how to fix this.

[jackthake]

Im getting an error where it tells me to change all the getters/setters to static... what should I do?

[dancross]

It is good to note that you have to import every method from your Artist class to your Boot class.

[goldfan]

when I run the code for the tile grid. Does anyone know the issue?
Please help
