DizzyAGE General Coding Queries

Not sure what you mean Boo. The behaviour in water is automatic depending on whether he has a scuba or not. It’s all dealt with in the Player.gs file (towards the end in the section titled waterplay) and called into play by the HandlerUpdatePlayer section in the Handlers.gs file when ‘the material inside the ‘player’ box is ‘water.

You can change how long he survives in water before drowning in the Def.gs file by changing the number in the #def AIR_LEVEL define.

The only extra bit some coders add is to add some extra defines to ensure that Dizzy respawns back to where he entered the water if he drowns rather than respawning in the water where he died.

Ahh right. I must have painted the brush/es wrong or something then. Thanks Grandad, I'll go check that out.

I noticed that :smile: . I gather you helped to modify Noggin's coding to make it smoother. It works really well! I'd like to implement that myself but I think I need to start with the basics so I can understand it, rather than just copying and pasting (which didn't work for me anyway, haha!) I noticed you left notes in your coding but maybe they were written in Russian? Because it shows up in Notepad as just symbols.

EDIT: Sorry, I thought you meant to say Last Hero and Jewel Thief had identical coding. They do though right? I forgot all about Home Alone, which I completed but never looked into.

The author of the game Jewel Thief took a scrolling from the game Dizzy - Night at the Museum. It is old engine, it is simple with a scrolling. Comments are written in Russian. New exactly so far in two games about which I told. Though the Night at the Museum 1.04 version is already ready, on new engine. Game became a little bit more difficult.

So I should have downloaded this before it was updated with complex scrolling! {yolkfolk}:sob: Well thanks anyway. It looks really nice so I guess I'll just play this for a while

Hi everyone,

I'm trying to understand parallax scrolling. I downloaded the brilliant Dizzy and the Jewel Thief, which does this very well, and the coding seems very complex. It has been smoothed, and has 4 layers. I'm just looking for a simple example (no smoothing; 2 layers a la Fantastic Dizzy) to get me started. Does anyone know of any other games that use this technique? (Besides Last Hero, which is also too complex for me :cry: ).

By the way, how do people feel about scrolling in general? I disable the Y axis, but even so (possibly due to Dizzy's frame rate, which I may consider altering if I can) it makes me feel just a little sick. I want to persevere though! I think the map can be made smaller with scrolling, as you don't have to worry about the layout of each individual room.

Hi Andy, when you say 2 layers, you mean just Dizzy's layer and a sky background? You can find that in Pirate's Life Dizzy and it's very easy to do.

If you want to add more layers without the smooth scrolling, I can tell you how to do that - it's not that hard if the scrolling is only horizontal.

I don't understand how the smooth scrolling works either - Dr Titus posted an edited version of Jewel Thief here:

The version you've got is that one with a few tweaks by me. If you want to see what the game looks like without the smooth scrolling, go into the game options and set the scrolling to stiff. The jerkiness is because Dizzy always moves horizontally in multiples of 4 pixels. There's no easy way round that - Dr Titus' technique is very complicated and my best effort, in Don't Panic Dizzy involved completely changing the player movement file so that Dizzy moves in multiples of 2 pixels - I don't recommend you try that. Even if you looked through my code, I had to make modifications all over the game code - I can't remember where they all were.

I'll have a look and see if I've still got an old 1.0 copy of Jewel Thief if that helps.

Thanks a lot! Silly me, I forgot about Pirate's Life! I've been messing around with this for about an hour and I think I'm starting to understand {yolkfolk}:thumb:

EDIT: Yes, I meant Dizzy's layer + sky background. I probably should have figured it out for myself, as I've disabled vertical scrolling so it's just a case of matching the background to Dizzy's X coordinate (minus whatever number so it lines up). I guess adding extra layers is the real challenge. (I don't want to use smooth scrolling, although I can see it's great, just because the coding looks way beyond me.) I'll have a go at extra layers myself, and maybe pick your brain when I inevitably fail :smile:

Parallax scrolling is different layers scrolling at different speeds to create illusion of depth. Or at my low level, just keeping the background screen static while the landscape scrolls (although I suppose it's technically the other way round). Maybe something for DizzyAGE 2.4? {yolkfolk}:raspy: I might abandon it because Noggin, you're right about the jerkiness. I've just given myself a headache after a few hours trying this out. This is what I have for now (in the handlers.gs):

// scrolling games support
if( GameGet(G_VIEWPORTMODE) )
{
roomw = GameGet(G_ROOMW);
//roomh = GameGet(G_ROOMH);
GameSet( G_VIEWPORTX, GameGet(G_ROOM X) *roomw - PlayerGet(P_ X) + roomw/2 );
//GameSet( G_VIEWPORTY, GameGet(G_ROOMY)*roomh - PlayerGet(P_Y) + roomh/2 );

dx=PlayerGet(P_ X) ;
dy=PlayerGet(P_Y);
sky = ObjFind(10);

ObjSet(sky,O_X,dx-120);
}

Hugely technical!! {yolkfolk}:yahoo:

Yeah, it's a shame about the jerky scrolling.

It might be worth persevering with the smooth scroll code - I've incorporated it into games without understanding how it works.

If you're copying it from Jewel Thief, you'll have to cut out all the bits relating to the extra layers of parallax (a big long list of objects) - you should spot them easily enough, I used a variable called G_PARALLAX! And there's a second bit of code in the util.gs file to copy over as well.

I don't think there's much else you need to do to make it work actually... {yolkfolk}:scratch: You've just got to find the analog to your bit of code for the backdrop (probably tacked on the end) and change the object number.

Give it a go anyway - scrolling games are much better than flipscreen.
