Depthcharge
Had a crazy idea of creating a simple arcade port in 1 day using scorpion.
The result was a nearly but not quite! Thanks also to earok for clearing up my ammo variable mess anyway ![]() Instructions: Left & right to move ship, drop depth charges with fire (left & right) to destroy subs before timer runs out. You have 90 seconds to get over 500 points, if achieved you get overtime of 45 seconds. If you are hit by a sub mine then your score is cut in half. If there is any interest in the project I will try and get around to finishing it off properly! To do: More score subs Fix some animations Prevent subs appearing at the same depth at once Works on OCS but has slowdown unfortunately. ![]() us img vs non us img File is in the zone! Edit - Quick bugfix, hope it no longer stops respawning player, if so let me know! Last edited by acidbottle; 27 March 2022 at 19:05. |

I remember this was one of those game in the arcades that had the retro decoration (at least on the Taito and Model Racing version called Sub Hunter), you could try to add that

Thanks for sharing the video, spotted a bug with player respawning which snuck in somehow! Hopefully fixed now.
@saimon - Yup, Sub Hunter, absolutely wanted to, sadly I cannot find an image of this overlay anywhere. If anyone has it please pm me ![]() |

Oh, splendid. I have a real soft spot for Depthcharge and only recently discovered a (bad) Amiga port, so am very excited to see this one.

Have had a play now and it's an excellent start, so I really hope it gets finished.

Nice one, glad some have not only remembered but like the game! Made a bit of mess of some things (rushed it) in the first version, so began fixing one or 2 things last night. This includes the depth charges no longer lagging or delayed, will now operate properly depending in which "direction" you last moved, keeping it playable for single button controllers.
Will have a proper bash at finishing this off though, the main challenge will be getting each sub to spawn at a different depth while on screen, if anyone has any tips or algorithms ... ![]() |

I like this!
I haven’t played the original, but maybe a port for bbc micro.. random spawn heights should be simple enough I.. think? Maybe a random y number with a dice in the onspawn codeblocks? If they’re not supposed to overlap each other it’d need some extra logic to make sure they don’t appear in a range close to another one somehow, hmm. Or just pre set a bunch of heights with in use/unoccupied variables.. ? I’m not really sure. The verticality of the charges makes me wonder if sprite multiplexing is useful but I don’t understand that really. ![]() |

He's okay. But he's not going to post anything now I think, as he announced. But a moderator could edit his post... or maybe own it / transfer it to some active member.

Cheers Mixel
![]() The subs appearing randomly works great, have aborted a couple of attempts at in use and occupied styled logic for depth, its probably quite simple but will figure it out eventually! Glad you like it though, sometimes these simple things are quite fun in short bursts, like flappy birds, pac man etc. The arcade audio, at the time, was incredibly atmospheric and am trying to capture that element also. Damian was indeed banned it seems, there is a thread somewhere about it, for more clarity. |

Well done!
Would you consider adding project source etc to the unofficial Scorpion Engine demos repo? Happy to give you access. |

![]() @saimon, I had seen a sketchy YT video of someone playing it a week or 2 back, cannot find it again for the life of me though! Update: Most game and animation bugs appear squished, am sure I can break it again though .. Added some polish, mainly with the addition of a demo/attract sequence! Really just leaves needing to get that sub spawning code nailed. |

A proper two-fire-button option would be nice too

Update:
v.02 dropped into the zone. Still a work in progress but resembles a playable game now! High score subs now remain near the bottom depths. |

This link is from face3book and is a report - in italian - about Sub Hunter as being a joint venture between Taito and the local distributor Model Racing; if the video does not work let me know; will ask for scans or pictures of the background |
