Eh, I would test it out but I don’t feel like downloading tiny sound… Maybe later I’ll take a look at it and tell you what I think! I downloaded the actually library though.

#42

why dont you use the newer javadoc version? this is the old one

#43

Better use JavaDoc 7

#44

Hey wes,
Check your email!

#45

You really couldn’t of just sent him a message?

#46

A camera is a must with practically any good graphics library.

#47

Scaling, positioning, rotation control over all the low level features like the matrices. Frustum culling and hmmm… I’ll think of other stuff!

#48

Well, I tried to play your game but I received this error:

That’s unfortunate as I wanted to see what your library is capable of :confused:

Edit:
Did you only compile your game for Linux? The error is just saying it can’t find the natives. I’m running windows, so that’s why.

#49

Sorry, but I have another error, I think you’re not handling the actual paths correctly to your resources!

Edit: Oh its fine if the game isn’t all that awesome, I just want to see what you can do with your library! I’m currently working on my own for a special project :slight_smile:

#50

Did you upload the new one? Because I’m still getting the same error when running it :frowning:

#51

Nope, sorry it just isn’t working :confused: But I’ll let you go now, maybe you can figure it out tomorrow!
Edit:
I took a peek into the jar file, and there is no res folder! The game is trying to access one though.

#52

No idea, sorry, but its not working :confused: I swear, I even searched for a res folder using winzip in the jar file, but it didn’t find one! Are you sure you’re exporting correctly in eclipse?

#53

Maybe you are having a res folder besides your jar file.

#54

Ah yes, it finally works! Wasn’t much of a game, but cool enough :D! That background is really trippy!

#55

Nice update!
MERCury needed a camera, and I love the scaling, wish my engine had that!

#56

That’s what we have [icode]glLoadIdentity()[/icode] for.

Also: ALL matrix operations (except obviously resetting/replacing the matrix etc.) multiply the matrix. That’s how matrices work.

#57

Woah, you’re getting far!

I browsed through your code and things are looking very sleek (very smart idea with a static resource manager by the way)!

#58

Wow, im impressed. Can believe how much work you put into all those different media sources! I love the tutorials, really helped me understand how to use mercury, and the animation/spritebatching is awsome. (+1)
What are you planning to do next in MERCury, and furthermore, do you have an idea of what the finishgd product will look like?

#59

I’ve got to admit, I’m impressed! You seem to have learned a lot over the past couple of months, and its starting to show in your work, good job!

#60

Same here, he’s progressing faster than I am with my old library. :frowning:
