I am used to 1.7.10 modding but I decided to move forward to 1.8(I know that the current game version is 1.16 but I'm nostalgic) and I'm having errors on the ore generation at these lines:"WorldGenMinable gen = new WorldGenMinable(block, vienSize, generateIn);" and "gen.generate(world, random, xRand, yRand, zRand);". The error for the WorldGen Minable is:"The constructor WorldGenMinable(Block, int, Block) is undefined"  and for the gen.gererate;"The method generate(World, Random, BlockPos) in the type WorldGenMinable is not applicable for the arguments (World, Random, int, int, int)". I decided to ignore them and run the game but as I was creating a new world, I got a crash report saying :

1.8 is no longer supported on this forum.

Please update to a modern version of Minecraft to receive support.
