A very minor thing:

Where:

TARGET_DATA = server.getAITarget(object_id)

The TARGET_DATA.character and TARGET_DATA.vehicle should be an integer and NOT a float.

Problem:

TARGET_DATA.character and TARGET_DATA.vehicle are floats.

Solution:

TARGET_DATA.character and TARGET_DATA.vehicle should be an integer.

Back in the day, this was bad because the game cared about types.

now it is fine because it still works (most of the time).
