Help With Ore Gen With Custom BiomeDecorator


Emerald_Galaxy

Recommended Posts

So I have been tinkering with my new BiomeDecorator for my custom biome, and I noticed that my custom ore hasn't spawned since I changed the decorator. I have no idea how to generate my custom ore with my BiomeDecorator. Can someone please help me?

When you run into a problem like this, I don't know why people ask for help without simply trying to observe what is happening. Programmers don't debug by simply looking at code, rather they "trace" the execution. You have two ways of doing that (1) use debug mode in Eclipse (or whatever IDE you're using) and set breakpoints in interesting parts of the code and see what path the code takes, or (2) use console or logger print statements to print out what is happening.

 

For example, how come you haven't put any print statements in your decorator methods? If you put some in you can confirm which methods are being called. For example, do you even know if your generateOres() method is being called? Just put in a print statement!

 

And your print statement can have extra information in it like values of important variables. 

 

If you don't like print statements you can do same thing by setting the breakpoint for the method and then stepping through the execution. 

 

Please do that and it should be obvious what is happening. But if you still can't figure it out post what you find and we can help.

You know, now that you point it out, I feel stupid for making this the first thing I do when I can't figure something out, or I have a problem. And I feel bad for not doing that first. I'll take your advice and put some print statements, then tweak the code a little to see what I can change.
