| Unit5 -> Plant2 | Unit5 -> Plant2 | ||
| - | which is implemented by the following code: | ||
| <code> | <code> | ||
| local unitToPlantMap[uid] = create (; dataType=integer, dim=unitID, data="1 2 1 1 2") | local unitToPlantMap[uid] = create (; dataType=integer, dim=unitID, data="1 2 1 1 2") | ||
