After 3 years, 6 months, 2 days and 20 hours (give or take), the old SecretRoomsMod is getting another release, for 1.12.2. I've compleatly rewrote the mod for 1.12.2, using only the textures and ideas from the original. Ive also added some new things, for example:
Secret Room Blocks dont have to be full blocks. Now the Secret Rooms Blocks wont default to stone when you place it on a non-full block block. The colliding box and select box will also change accordingly. The Secret Rooms Block will also change its own state accoding to its surronding. For example with fences
Switch Probe. An item used to change the texture of a Secret Rooms Mod block. Click on a non Secret Rooms block to set the texture, then click (or shift click for doors/trapdoors/chests) on the Secret Rooms block you want to change.
Exposting Helmets. Wearing this helmet will tell you where Secret Rooms Block are.
