		chanceToGeneratePatch {Number} Integer : The chance to generate the patch (random between 0 and Input) - WILL BE RUN IN MODTICK - lower the number, more will generate
		chanceToGenerateInPatch {Number} Integer : The chance to generate in the patch (random between 0 and Input) - lower the number the more will generate
