Factorio Forums

As title states, implementations of the ReactorPrototype can't be rotated in game. Rotation is irrelevant to base game reactors do to symmetry, but was playing with various heat mechanics for a mod and ran into this.

Thanks for the report however this is not a bug. You are correct: reactor prototypes cannot be rotated because they do not support rotation because they do not have a direction.

Is there a particular reason they don't have a direction? There is nothing I'm aware of at the prototype phase that would prevent that.

It was not needed for base games implementation of nuclear reactors and every additional feature on a given entity is additional time, complexity, and potential bugs that have to be dealt with over the lifetime of Factorio.

Similarly trees, ores, biter nests and many others do not support directions.
