Pix Engine: Platformer Engine

[Jovanny]

@pumpkinhead

You would do this by using a Uint8Array

I was looking for these kind of things in js, and I was under the impression that I could not manage to have a fixed 8bit element array type… if this exists, then the hit in memory would almost disappear.

Within the engine, every platform, door, etc… is represented by a number within that array… if we had a huge Level, we would need to have 255+ platforms or walls to get to 8 bit element limit… Within this demo I have 53 as a maximum number… I could see levels with more than 255, so I think that 16bits array should be the way to go…

@pumpkinhead

For example, to initialize the array you would write

this.table = new Uint8Array(Math.ceil(this.maxCol * this.maxRow / 2));
// divide by 2 since each byte holds 2 elements

and to extract the higher and lower 4 bits of each byte you would write

var byte = this.table[i];
var hi = (byte >> 4) & 15;
var lo = byte & 15;

Update: Thank you… I think you are into something here… I’ll take a look to your approach:

@pumpkinhead

As far as I know, it only uses these pointers to get the class type of the platform.

Not only the type, because I need the instance as well… the instance has data like position, platform friction for that specific platform etc…

[Jovanny]

Thank you @pumpkinhead… It seems that js uses 8 bytes to store a single number… We may be improving the mem alloc 4 times by using a Uint16Array which allows the engine to store at least 65535 different platforms, portals, collectibles, etc… per level… which is more than sufficient

[Jovanny]

Here is what I ended up doing… It will be asking for more memory resources based on end-user needs…

[Jovanny]

I’m still very busy, but from time to time I’m working on fixing bugs and adding stuff. There is a lot to do, but I’ll be releasing the first version of this engine most likely within the next month, so stay tuned.

how do I get rid of the grid in the bg when I press play?

[Jovanny]

That will be discuss in the next tutorial. You are running the engine in debug mode. I’ll tey to put together the next one for this tuesday at ETC night.

[gamer_boi]

it bugged out and now it wont let me place anything

[Jovanny]

Yup, it is important to save your work constantly… but in most of the cases for 1.19.4, you should be able to refresh the page and reload the work if you only have one wick editor tab open at the time.

[gamer_boi]

this engine works really good and I like it, I would still rather use @awc95014’s engine tho because its easier to work with and the one downside to your engine is that you have to be ultru precise on where you place the blocks and it is takes a lot of time to actually make something with it. im not trying to say that your engine isn’t good or anything, Im just saying that its a little too advanced for me and it just takes a bit too much time for me.

[Jovanny]

Yes, we have now 3 to 4 platform engines to use. I love @awc95014 engine as well.

[Jovanny]

@gamer_boi

to your engine is that you have to be ultru precise on where you place the blocks and it is takes a lot of time to actually make something with it.

You could also try to decrease your pixUnit to 1. So then you dont have to be that precise anymore. The downside is that requires more memory from your machine.

Hey @Jovanny I made a little platformer, adventure game based off of Hollow Knight using your engine & I was wandering if you can either implement or teach how to add wall jumping to my character.

i know that i have not posted anything on this forum and i will not but i have no idea how to do any of this and i just wantto say yall are amazing and that i respect all of your hard work so much and to scrool through it at the beginning it was a bunch of rectangles and now it is actual like objects so i want to say congradjulations on your develop ent of the game and also keep up the work guys and good luck(

[Jovanny]

Sorry, I didn’t program that part, but it is on my list for the future.

[Thunderstorz]

Heres the .wick file if you want to play the game

Alright, time to emerge from my vast slumber to compliment this amazing project. This engine has many possibilities, and the camera system is brilliant!

[Thunderstorz]

There’s an easter egg, you may have seen it in the editor (that’s why I wanted to export it as an html) but see if you can get down there without CHEATING.

[Logan_Jordan]

OH MY GOSH this game is amazing yall are phenomenal I wish I could contribute to this production but I don’t have these skills I do have a place you can show them in my talent show place it would be my honor to have some of your some of your work in my talent show and there may be a prize

Stick animation talent show (OPEN)

Hellow i am new to wick editor i started in october of 2022 and i have made a few cool pieces but i want to see how good other user are HOW TO SUBMIT upload gif and name of animation (REQUIRED) upload wick file of the animation (HIGHLY RECOMMENDED) upload storyline (OPTIONAL) Plagiarized work will not be scored and will be exempt from the grand prize …Oh i forgot to mention the prize? the prize will be an animation made by professionals that you can edit.
