GOTEK/HXC/FlashFloppy USERS => i encourage you to update your firmware if you wanna use the DSK version of the game, or use HFE to avoid firmware bugs
Ooh, looks interesting! I really enjoyed Defence from Shining, but there's more than enough room for another CPC tower defence game in my life...
Looks really really promising!
oh wait, they change routes? wtf! :D :D
I rewrote most of the graphic engine, huge optimisations, refresh is heavily faster (it's was already fast :P )
The findpath is clever. The shortest path is the goal of the ennemies but it's unpredictable when there is more than one optimal path
There is also new towers so now we have
- simple touret (single hit)
- bash tower (simultaneous hits)
- frost tower (slow down ennemies)
- swarn tower (hit only flying ennemies)

Looks great. I love the HUD font, too!
perhaps the background tile could be simplified a bit, I think it's going to drive some people with astigmatism crazy :D
First public beta released in the very first message of this topic, enjoy!
Need 128K and all gate array banking schemes
6 channels music on playcity / 3 channels music not in this release
Recommended emulator => CPCEC from CNG http://cngsoft.no-ip.org/cpcec.htm (enable playcity in F10 menu)
Mmmh, did you try this on a real CPC?
I played a bit without the Playcity and it seems very cool.
However, I then plugged my PlayCity and the CPC crashes after the "gate array" test (vertical bars filling the screen). I tested my AT2 Teaser which uses the 9 channels of the PlayCity and it works fine.
Now I don't think the PlayCity can make a CPC crash when badly accessed to, so maybe something else?
I tested it on a real CPC without playcity as i do not own one of this!
The detection code used from basic is
org #8000
di
xor a
ld hl,(#66) : ld (sav66+1),hl
ld hl,(#68) : ld (sav68+1),hl
ld hl,#01F6 ; or 1
ld (#66),hl
ld hl,#45ed ; (inverted) opcodes for retn
ld (#68),hl
; If a Playcity is present, the code generates a NMI then stops the counter.
ld bc,#F881 ; 3 NOPs CTC channel 1
ld hl,%00010111*256 + 2 ; 3 NOPs A NMI every 8 NOPs
out (c),h ; 4 NOPs
out (c),l ; 4 NOPs
; not too fast...
ld d,5 : dec d : jr nz,$-1
inc hl ; 2 NOPs L=3 => Stop CTC channel
ld d,5 : dec d : jr nz,$-1
out (c),l
ld (#FFFF),a
sav66 ld hl,0 : ld (#66),hl
sav68 ld hl,0 : ld (#68),hl

As for the game, it's really cool. I managed to get to level 53 in Easy.
The Medium is much harder, you die right from the start if you don't use the right combination. Maybe a little too hard?
As for Hard, mmhhh, I couldn't survive the first wave :). Is it possible? With only one tower?
- Ah, AZERTY "M" key isn't well mapped, you must type ",".
- Is it normal that Space bar freezes the game? Is it a pause? Seems like cheating :).
- Do you think a "accelerate" game key could be done? When the wave is sure to be destroyed, it would be nice to go faster to the next wave.
- The background tile is maybe too hard on the eyes. Maybe a possibility to change it on the fly or at the beginning?
- A "suicide" option (with validation...) could be handy.
Great stuff, well done!

As i wanted something simple and AMSDOS compliant, i will forget the detection and the user will choose No music, 3 channel or Playcity

If you cannot pass the first wave in hard level, maybe the medium difficulty is perfect ;D
Just put a tower anywhere between the 2 arrows

I'm waiting key release to avoid side effect (tooooo many ennemies freed at a time, you will lose for sure) => i may auto-release the key
Sometimes you (we) want to accelerate when there is many things on screen, that's not really possible as the CPU is full
When there is almost nothing on screen, just press spacebar to release ennemies so the answer is no
For suicide, i guess delete some towers is enough but hey, it's possible to manage ESC key ;)
Thank you!
new beta in the first post
- space auto release- ESC to quit ingame- no moar Playcity detection + No music mode

AH! I knew I wasn't crazy. When playing Hard the first time, the wave can be killed with one tower. But if you played any game before, the monsters are tough! It seems starting a new game doesn't reset the monster hit point. I suspect a bug!
The Playcity now works, very nice tune (although maybe a bit short). I'm having quite a lot of fun on the Hard level.
Oh, do you intend on adding sound effects on the 3rd PSG of the play city? Could be a nice touch.
Wave 39 on Hard! Not so bad :).
Quote from: Targhan on 19:52, 05 March 21

No sound FX because the game has maaaaaaaaaaaaaaaaaaaaaaaaaaannnny hits quickly
Maybe some Bip when you lose a life?
Maybe not shots, but enemy appearing/destroyed, lose life, tile built/removed/upgraded. Add a key to toggle the SFX if the player thinks they're getting annoying. Keep the sfx low volume and it should be great.

good suggestion. That said, i will need SFX and i'm absolutely not expert for that. You have a few minutes for me? ;D
The musician did a great job, why not ask him to do the SFX too?
Quote from: Targhan on 21:05, 05 March 21

because that's a completely different job. That's why i made wav2ay tool !
btw: ennemies energy reset will be fixed soon
My suggestion is that he learns how to do it :). He can at least try! Wav2ay is not always the right tool. It can be working for samples, but for short electronic sounds, nothing beats a human to create the SFXs. Come back to me if it doesn't work out.
new beta with the important bugfix of ennemy life reset between parties :picard:
Just gave version 3 a go, nice! :)
I do like the odd strategy game so this is good to see. It looks promising though at the moment the game doesn't seem to hold much challenge once you 'work it out' so I hope the extra ideas you talked about adding will help with that.
Out of curiosity, in what way is the game scaling beyond wave 100?
It would be interesting to know a little more about the effects of the upgrades. The range increases are obvious, but some upgrades don't increase the range and I cant tell if they're firing faster or doing more damage, or just a way of making you pay more to get to the next range increase.
If you'll forgive a couple of small 'requests', I know it's already been mentioned, but I have been finding the ground tile a little distracting, so it would be nice if it could be a little less 'prominent' in some way.
Also, I sometimes found it a bit fiddly to position the cursor because the repeat rate from the first press is high - I often ended up moving two tiles instead of one. Any chance of a slightly longer delay on the first repeat, or an option to adjust it?

thanks
about the cursor it could be nice to use SHIFT+cursor for fast move and cursor for one move
about upgrades and so, there will be a documentation but i'm not specific now because i'm fine tuning difficulty of the game
hard mode is a bit too easy (for confirmed players)
beyond wave 100, ennemy life keeps growing up, in easy mode it's almost impossible to reach wave 250 (it's 16 bits so...)
new tower in progress ;D

Well, you're a better player than myself, then :).
As for ideas, how about monsters that can destroy your towers? :).
Quote from: Targhan on 13:09, 06 March 21As for ideas, how about monsters that can destroy your towers? .
Funnily enough, I had had a similar thought, but I wasn't game to say it because it also sounded annoying. :laugh:

Because that sounded like a challenge, I thought I'd see how far I could get in hard. Ended up making it to Wave 283! :D After about wave 200 or so though I was not much more than a spectator as I didn't have room for any more defences and they were all fully upgraded. Just occasionally deleted a turret to replace with extra air defences as the small flyers were getting obscenely tough, which were eventually what got through.
soon
engine may handle up to 768 sprites simultaneously
3 channels music for regular CPC and 6 channels music for Playcity owners
(https://i.postimg.cc/RN9YLSjk/20210531-171947.jpg) (https://postimg.cc/RN9YLSjk)
GFX may be enhanced before release :P
Dunno about the 768 sprites but that loading screen is amazing.
please please PLEASE make this work on a 64kb machine. I don't care if it doesn't have sound, I just want to play it on my 464 ;_;

@roudoudou (https://www.cpcwiki.eu/forum/index.php?action=profile;u=1714), how do you detect that your game is running within an emulator? :-)

Because emulators are not accurate and because floppy disk controller keeps some undocumented secrets ;D
Btw running on a real machine will display another GFX 8)

Hi Roud,
Really great & addictive game.
Best & thanks again for the game.
Quote from: tronic on 13:32, 04 June 21
But, to get it working on CPC, i was really annoyed by the ùcpm/sector/fastload/emulator-test trick.
It's not an emulator test but a CPC test (there is 2 GFX, one for emulator and one for CPC)
So you dump memory and remove Cat'Art (thanks :( ) and Artwork of the game :(
You put a comment on RasmLive =>
I did not know if you plan to release another format or sourcesDid you ask?
About DSK and your old HxC, it's perfectly normal => upgrade firmware or use HFE

Here is a very standard floppy in order to create OTD floppy
I tested loading from floppy to floppy but it may work straight from M4 if you copy all files in a subdir
there is 2 basic programms
first
RUN"FORMAT
it will format a floppy for OTD
then
RUN"MAKE
it will load files, ask for OTD disk and will write files
then it will ask for source a second time, follow instructions
there is an automatic CATALOG at the end, it may fail because Amsdos may still believe the floppy is a DATA floppy, just press (C)ancel and retry CAT (a proper reset may help)
Hope this will work for you :)

the problem seems to be the M4 because M4 is not a regular expansion card, it's kind of supercomputer playing/overriding electronic signals at high speed
So while waiting for an "official" new release ... here's a SNA file from CPCEC made on my Pi400 ... works fine on 6128 + M4 ;) :D

Hi again Roud,
Ok i do understand now & know it's "too late" but i deleted on this side too and everywhere.
FYI : As above, the "create odt dsk" tool you posted didn't work for me too... And i have tried... Many times...
Releasing a game on this way is fun on a coding side but too complicated for end users.
Well... Waiting for the next one...
Bisous !
This version should work on all Mass storage, thanks to @Ast (https://www.cpcwiki.eu/forum/index.php?action=profile;u=573) who was faster than me to do it!
(btw there is no more FDC testing and the screen is "always" as on a regular CPC)
RUN"OTD
works on all support including, x-Mass, M4 & Albireo, + discs drives & Gotek too.

Ok, here is captured from real hardware, It is the first time that I also capture audio from the playcity, and it is heard lower than normal music, I do not know very well why, and I have recoded the video, sacrificing the video quality a bit, so that it occupies less.
the volume may be "inside" the song as there was 2 musicians (one for each version)

You need to reach very high levels after winning for this
Can I expect it for the 768th wave of ennemies?
At the moment, I am at the 605th wave. I played it for 10 hours non stop.
Hi guys. Hope you're doing well.
Last two nights have been a bit short but the PlayCity version of the main theme is finally finished. You can find it on my SoundCloud. Hope it will be added to the game by Édouard Bergé soon. The AKS module still needs some serious cleaning before it will be added to the repository and might include a small surprise for ASCII Art lovers 😉
Happy Sunday to everyone.
