Version analysis of SHIP_ROCK_HERMIT

This code appears in the following versions (click to see it in the source code):

Code variations between these versions are shown below.

Name: SHIP_ROCK_HERMIT Type: Variable Category: Drawing ships Summary: Ship blueprint for a rock hermit (asteroid) Deep dive: Ship blueprints

Code variation 1 of 4A variation in the comments only

This variation is blank in the 6502 Second Processor version.

The ship blueprint for the rock hermit reuses the edges and faces data from the asteroid, so the edges and faces data offsets are negative.
.SHIP_ROCK_HERMIT EQUB 7 \ Max. canisters on demise = 7 EQUW 80 * 80 \ Targetable area = 80 * 80
