#Blocks Infected crops are regular vanilla or mod crops (wheat, carrots, potatoes, etc.) that have been contaminated with a pathogen strain. The infection affects the crop's drops - infected crops have a chance to drop contaminated items that can spread the infection when eaten or planted.

How crops become infected

Method	Description
Contaminated Substrate	Right‑click an inoculated Contaminated Substrate on a mature crop. The substrate is consumed, and the crop becomes infected.
Placing infected seeds	If you plant a seed that has a pathogen strain in its NBT (e.g., from an infected drop), the planted crop starts infected.
Natural spread	Infected mature crops can spread the infection to adjacent mature crops (randomly, based on random tick speed).

• Only crops in the bioforge:infectable_crops block tag can be infected. This tag includes vanilla crops and any mod crops you add.
• A crop must be mature (its age property at maximum) to spread infection.

What happens to infected crops

• Drops - When you break an infected crop, the event is cancelled and custom drops are generated.

  • The original crop drops (e.g., wheat, seeds) are calculated via Block.getDrops().
  • Each drop has a chance to become contaminated based on the crop's InfectionStrength (a value between 0 and 1).
  • If the drop is contaminated, its NBT receives the strain data (without the colony ID - the stripColonyId method removes the colony UUID part, leaving only pathogen type, transmission types, and symptom values).
  • If the infection strength is low (≤0.0) or random chance fails, the drop is clean.
  • The crop block is replaced with air.

• Eating contaminated food - If you eat a food item that has a strain NBT and that strain includes FOOD_BORNE transmission type, you become infected with that pathogen (symptoms applied).

• Planting infected seeds - If you plant a seed that has a strain NBT, the newly placed crop block is immediately infected with that strain (via the CropInfection capability on the chunk).

Spreading mechanics

• Every 20 ticks (1 second) on the server, the spread handler runs.
• For each loaded chunk, it checks all infected crop positions.
• For each infected mature crop, it attempts up to 3 times to spread to a random neighbouring crop (same Y level, within 1 block horizontally).
• The chance per attempt is (randomTickSpeed * 2) / 4096 (scales with the game rule randomTickSpeed).
• If the neighbour is a mature, infectable crop and not already infected, it becomes infected with the same strain.

How to detect infected crops

• There is no visual difference in the crop model - you cannot see that a crop is infected.
• You can use a Swab on the crop (right‑click while holding a clean swab) to sample the infection. If the crop is infected, the swab becomes contaminated with the strain, and you get a message: “Swab contaminated with infected crop strain.”
• Alternatively, you can break the crop and look at the drops - contaminated drops will have obfuscated NBT.

Tag requirements

• bioforge:infectable_crops - block tag. Add any crop block that can be infected.
• The crop must have an age property (integer) to determine maturity. The handler finds the first property named “age” and assumes the max value is the mature stage.
