This is a little test demo, for some basic enemy AI.

The enemies are fishies, and they attempt to attack you.

- When going directly up or directly down, fish don't seem to notice you.
- Fish take a moment to notice you - not a bug, this is how they're designed, their line of sight process runs only once every 25 frames.


All fish near or onscreen are selected and 'switched on'. Some states are tested, such as how far are they from the player, are they roughly facing the player.

If they're facing in the player's general direction, they will then run a Line of Sight routine, to determine if they can actually see the player.

Finally, based on their environment variables, the fishies will either swim idly, or chase you.

The main reason I'm testing this: Please see if you can find a way for fishies to escape the water and fly. The water is defined by a series of flat 'water' objects which line the surface of the water.

Currently, you cannot hurt the fish, nor can they hurt you.


Run = Left/Right
Jump = Shift
Punch = Ctrl (hold it down or tap it)

Any opinions, thoughts, suggestions would be appreciated.

(note: Screenshots are from an earlier version, the update looks a little better).

New In Update 11 March

Squirrels don't move yet, but do spot you and chase you. Their code is very much unfinished.

Problems with entering/leaving water should be resolved.

Also, I'd like your opinions on the music. I've converted the MIDI into an MP3 using some soundfonts, but I don't know if you guys think it's worth it or not.

It sounds VERY much like a normal MIDI, just one or two instruments are a little clearer. I'm not decided yet.

this is pretty good, but in my opinion the fish should move a little bit slower, it is impossible to outrun them. and after the fish atack you once, mabe they should swim away, then attack agian just to let the player get a chance to stay alive (if they could hurt you) but i like it, especially the turtle graphic

music rocks!!!!!
Posted by DeadmanDines 4th March, 2008

Lol, I can't claim any credit for the music alas, but do you think it's ok having it as an MP3 instead of MIDI? I dunno if the soundfont thing is worth it.

Adam: Thanks! That's a very good idea, I may just try that! Especially the swimming away thing.

An idea: Maybe they should swim till they overlap you, stop, bite, then chew for a moment before they swim after you again.

I'm inclined to keep their speed and just give the player a way to fight back. One aspect of the gameplay will be a little water firework you can use. You drop it in water and it fizzes around attracting the fish... while you jump in the other side. Could make it more tactical?

I think you should make pirahnna and have them take bites outta the turtle.

Bitemarks would be funny. Doesn't need blood though,
as it would be cartoon-like, and comically styled.

If there is a way to take chunks outta active objects
like how you can with the background objects, that would be neat to see.

Whatcha think ?

Fraid it can't be done

if you need help with the swimming away thing i might be able to help, im not the best programmer but whenever my brothers need help they always make me do it Image

Ps. That water firework idea is awsome

-The fish movement just looks like Always---> Look at turtle 0,0 at the moment...

Also their sprite is a bit off... not near the standard of the turtle sprite. Also if they pirahnnas they shouldn't look like goldfish >_< Mind you, you didn't seem to say they were, that was just MBK

Edit: Forgot to mention I don't like the large,fast camera movement when changing directions, made me feel kinda giddy.

Lol, yeah, that's exactly what the fish movement is

...but hey, it works!

I attempted to make the fish ok, but I know what you mean - I don't work well with characters of very very few pixels. The Tortoise was about as small as I'd like to get in terms of animated characters.

The intention was to make them look cutesy. So people will play the game, plunge into the water and think "Aww, cute little- ...AAARRRGH!!"
Posted by Ski 8th March, 2008

>_< well perhaps set the fish movement to 0 when he reaches the player so they don't just "vibrate" ?

yeah, I have done now, I'll upload the new version for comments

A fish also just followed me out the water from the right hand side-opening.

DOH. I may have fixed it, but I'm glad people are still testing this, cos it's only with rigorous testing that it can be resolved.

EDIT: New version uploaded, please test, ye all
- Fish now chomp, to give you a chance at escaping.
- Fish don't crowd and buzz as much as they did when all together.
- Slightly altered attack animation.
- Graphics - new background, and a squirrel or two.

Works for me? Try again, if it still plays up, I'll try sorting it tomorrow.

EDIT: Just a note I forgot. The URL is different. I've updated the download details above, so just redownload it using the URL given above, and you should be ok.

HOW, lol, my anti-swim-in-air routines- i thought there was something fishy about them...

Any ideas how?
Posted by DeadmanDines 9th March, 2008

LOL, NOW I remember! I really should have blocked you from walking offscreen, shouldn't I!!

hey you know how adam swum in the air? well once a fish followed me into the air...... 0.o
Posted by DeadmanDines 10th March, 2008

Yeah, it's getting annoying that. It never used to happen, now it seems to occur with more frequency.

The problem is very much with how I handle entering/exiting the water. You pass a small bar on the surface which basically handles the 'in/out' change.

Because of this, it's extremely hard to tell if an object is actually underwater or not, because if it somehow misses the bar, it's almost impossible to detect.

I think the real problem is with using so many fish, and the bouncing ball movement.
Posted by Ski 10th March, 2008

yes, the bouncing ball movement is probably it
Posted by DeadmanDines 10th March, 2008

Think it's fixed, I'll upload when I've done a little more to the squirrels.

another thing you could have done is make the bar that changes it in and out bigger..
Posted by Peblo 10th March, 2008

Um Dines, that's not a good camera movement.
Posted by Peblo 10th March, 2008

You can walk on the bottom if you hold jump while entering the water.
Posted by DeadmanDines 11th March, 2008

I quite like the cam movement, what's specifically wrong with it? Too snappy? Don't like how it looks in front of the player?

I think the water problems are all fixed now, and I've uploaded a new version

The squirrels aren't finished yet, so they just moonwalk at the mo...

It feels very snappy and rough, very sudden.

Edit: but yeah, water works now

Dines, About your waterline ... Why don't you just test it to the vertical position the line forms at ?

-Mr. Sneeze-, I didn't say the fish are pirahnna.

I said he should make pirahnna, instead of those fish.

And also Dines, the biting thing Can be done, but it's tricky. You can't accomplish it in a normal way.

But you can get something that looks nice and I imagine close to the desired effect.

Of course you'd have to test position of the fish in relation to turtle, their biting attack animation, etc.

And then you'd need to make lots of extra "bitten" animations and combinations of them too that would play instead of the usual animations based on where bitten, ...

Well, doable but a pain in the arse.

I like the Screen movement like that btw.

It lets you see ahead a bit.
