i have created a custom grass block that extends GrassBlock, however, i cant make vanilla grass and saplings be able to be planted on it. i got plants generating on the block by overriding canSustainPlant() but it seems that for planting it requires the BushBlock method isValidGround() to return true. the problem is, isValidGround() is hardcoded to only return true to certain blocks (ie block == Blocks.GRASS_BLOCK...). would really appreciate it if someone was able to give me some insight into what could possibly be done here. edit: this is not an actual problem. i simply forgot to register the block as my custom class... for anyone that was interested simply overriding the canSustainPlant() method works to solve this.
