TearFlag

const TearFlag: object

Not Exported

For EntityType.TEAR (2).

This enum was renamed from “TearFlags” to be consistent with the other flag enums.

This is represented as an object instead of an enum due to limitations with TypeScript enums. (We want this type to be a child of the BitFlag type. Furthermore, enums cannot be instantiated with BitSet128 objects.)

Generally, the TearVariant affects the graphics of the tear, while the TearFlag affects the gameplay mechanic. For example, the Euthanasia collectible grants a chance for needle tears that explode. TearVariant.NEEDLE makes the tear look like a needle, and the exploding effect comes from TearFlag.NEEDLE.

However, there are some exceptions. For example, Sharp Key makes Isaac shoot key tears that deal extra damage. Both the graphical effect and the extra damage are granted by TearVariant.KEY_BLOOD.
