is it all possible to add conditions to recipes being avaliable

an example of what im trying to do (but failed in doing so) is

 

if(StorageMiningLevel.get(player).GetLevel() > 5){

    TestRecipes.instance().AddRecipe(new ItemStack(Items.stick), new ItemStack(Items.diamond));

    }

 

or

 

if(StorageMiningLevel.get(player).GetLevel() > 5){

    GameRegistry.addShapedRecipe(new ItemStack(ModBlocks.BlackQuartz), new Object[]{"QQ", "QQ", 'Q', ModItems.BlackNetherQuartz});

 

    }

 

long story short im trying to make crafting recipes only available on the condition that the player is the required level

but every attempt im making is making the game crash.....

 

is it all possible or is there another way around it?

 

 

 

Give us your main class - AND - your crash report.

are you asking for my main cause you assume thats where i register my recipes?

if so i actually have them in a separate file if that what your wanting, though if you need my main for another purpose i can provide that

 

crash report is as follows

 

A detailed walkthrough of the error, its code path and all known details is as follows:

hmm reading that, im not sure it will really work (im new so i may not be understanding it properly) but it seems those check and things are for crafting results in general you cant define item specifics in there, i need quite a lot of items to be crafted on the condition that the level requirement is met......

 

is there by any chance an on crafting event?

 

through use of packet handlers and  setting and changing nbt data that holds a value (level) ive crated a leveling system, its set up that i can retrieve that value through StorageLevel.get(player).GetLevel() ive used it for a lot of events before

 

what i want to do it have set values that items are able to be crafted,eg if level 1 then allow item1 to be crafted

if level two allow item2 to be crafted and so on

the thing you linked me to as far as i could interpret it was adding extra conditions to items being crafted but it seems like it couldnt be used to achieve what im trying to achieve

 

so would it be possible to use some oncrafted event if it exists?
