A_BabyMetal

The name "A_BabyMetal" refers to the arachnotron, which is known within the Doom source code as MT_BABY (or "baby spider").

A_BabyMetal is a code pointer used in the normal animation for the arachnotron.

A_BabyMetal is a wrapper around A_Chase that plays the sound effect DSBSPWLK before calling that other function. This makes the arachnotron play its walking sound while invoking the usual monster AI.

Uses

The A_BabyMetal code pointer appears in the following states in Doom's state table:

Frame number	Doom internal name	Use
635	S_BSPI_RUN1	normal animation for the arachnotron
641	S_BSPI_RUN7	normal animation for the arachnotron

Example

Codep Frame = 641

Or using BEX syntax:
