I love this video, and how it explains how scratch works. Most youtubers just try to make fun of it and say "How limited it is" but you described it very well in a way that makes it seem more like a game engine, which is what it is. Even if it is for kids, it does it's job very well, and i have been using scratch for years with no issues.

[@XenonNeko]

Thank you!

[@ego-lay_atman-bay]

I have been using scratch for many years, and love it so much, but I still don't say it's a game engine. It's way more inline with regular programming than a game engine. A game engine usually takes care of physics and more, but scratch just gives you the basic tools. Scratch does have moving in a direction, but that's already a common programming concept, turtle graphics.

[@DSMusicParodies]

btw, if u add multiple when flag clicked blocks, both run when flag clicks, allowing some scripts to be seperate from "wait" blocks in the forever loop of the other chain of blocks. this helps with things like snappy-ness.

[@XenonNeko]

Oh wow! That's neat!

[@flameofthephoenix8395]

@@XenonNeko Additionally you can use DaysSince2000 to create your own wait blocks which is a better alternative, and if you're worried that the wait blocks have more precise timing, they don't. Though, you'll have to multiply DaysSince2000 by 86,400 to get the value in seconds.

[@ego-lay_atman-bay]

Except you can run into sync issues. That's why many lot of scratch games use only 1 green flag clicked block (even griffpatch uses 1).

[@lpinf]

Just wanted to let you know, the forever loop isn't ONLY a forever loop, but it also yields for other "threads" once the end of the loop is reached (if you put multiple flag clicked blocks for example, those scripts would then get processing time), and automatically waits for the next frame. This means loops are capped to 30 fps by scratch itself, so you don't have to do any timing work ! The only way to prevent this is to create a function (define block) with the "run without screen refresh" option on.

[@ego-lay_atman-bay]

Well, scratch does cap it to 30 fps, but that doesn't mean lag can't happen. Using delta time is much better. Plus, this also caps the fps on turbowarp, which can run scratch projects at higher fps, as high as 256 (but usually just 60).

[@lpinf]

@@ego-lay_atman-bay Delta time is obviously superior, and for that, the `days since 2000` block actually is pretty cool if you want multiple timers (to avoid using the `timer` value which can be used for stop detection). It can get really precise, being a floating point number ! For small projects though? you aren't gonna lag scratch much, so it's fine.

[@breakdanc3]

I’ve always found that scratch runs on 32fps, but 23 on Firefox. Maybe it’s 24 because my fps project isn’t that good lol

[@lpinf]

@@breakdanc3 I've had issues sometimes with broken FPS caps of 24 on Windows in some browsers :p

[@breakdanc3]

@@lpinf Yeah. I switched my games to Google Chrome’s 32 fps, so it also works in the offline scratch program. I think most people use 32 fps for their games. I always used 23/24 until now.

[@Lu9_ST]

the funny thing is, one of the sample projects that would COME with scratch (the very old 1.x versions for windows) was in fact a Tetris clone. It had levels and speed-up I think, but otherwise it looked far more boring visually, so I'll still say yours is better, lol (but also old Scratch had less to work with i.e. you couldn't create and define your own blocks/functions)

[@PersonOverHeaven]

2 words USE CLONE

[@XenonNeko]

I personally feel that stamping is more efficient for tiles on a grid

[@PersonOverHeaven]

@@XenonNekobut with clones are way less complicated and can use the if touching blocks in sensing and rotate using movement blocks instead of all that math stuff and code

[@XenonNeko]

​@@PersonOverHeaven True. I'm definitely not used to the way things are done in Scratch 😂

[@flameofthephoenix8395]

@@XenonNeko Clones are easier, but not really the best for rendering, stamping is generally optimal, however clones do have their use case. Generally, clones are best used as extra data storage because if you make a list that is "For this sprite only" then clones will have their own separate version of the list that has different values, this is useful if you are storing a lot of data that can't fit on a regular list that only has 200,000 maximum items, though there is also a maximum of 300 clones so there is that to consider too.

[@snezitko]

​@@XenonNeko most things on grid that need collision detection are generally better with lists than using clones because the touching block is a lot slower than the check a thing in the list blocks.

[@OmarEssawyGD]

for your first time making an actual project on scratch, you did good

[@flameofthephoenix8395]

3:15 With that nice black background it should make recoloring your sprites easy, to change the color of the sprite you set the color effect to double the value you want it to be, to get the saturation you set brightness effect to one hundred minus the value you want your saturation to be, and to get the brightness effect you set the ghost effect to one hundred minus the value you want for brightness. I may have gotten some of the mathematics wrong since I haven't needed to use this in a while, but that is the overall gist. Unfortunately using ghost effect for brightness makes it hard to then have actual ghost effect.

[@flameofthephoenix8395]

1:13 In my opinion, it's best not to use triangles, 3d rendering doesn't need triangles, any illusion will do, and bill-boarding is an illusion. But, there's more you can do, like if you want to render a 3d line you can project the two points onto the screen then put your 2d image in-between the two points, scale it to fit between the two points, and rotate it to match the slope of the line.

[@bloxking7407]

AWESOME!

[@flameofthephoenix8395]

Alright, next I expect you'll be trying machine code, the best of all worlds, there will be no strange decisions from Unity, no weird block-based limitations, and a lot of time and effort spent.

[@Redfishvr124]

You are so underrated! It looks very good :)

[@oklyok]

there's a block where you can turn the sprite technically but not visually

[@flameofthephoenix8395]

3:00 You can recolor with the color effect block, however getting the colors you actually want is tricky.

[@playd43]

Adding a score is easy, just add a score variable and increase it every time you clear a line, and also add a top score cloud variable or a leaderboard.

[@XenonNeko]

Definitely! Although I'd want the game to control a lot better before I felt right attaching scores to it.

[@XenonNeko]

Since I was already there, I went ahead and added score and levels and speed increase (No leaderboard yet, though).

[@ClaramayNivetta]

i think it would've been cool to see the process behind implementing other game mechanics such as SRS, T-spin line clears, and back-to-back. you can most likely find more info about this by looking at tetris wikis and things, so i'll spare the details, though i still think it would be neat to see someone show the thought process behind programming those mechanics into the game

[@arsen4k]

14:30 cuz object wants to go beyond the screen, but scratch does not allow this and therefore moves the figure a little to the other side, but part of the figure remains behind the visible part ((for example, when a shape is rotated near the side of the screen, there is a chance that its coordinates will change, especially if they are J and L shapes and their long parts go beyond the screen)

So the thing about the "bag" is that getting 2 pieces in a row isn't actually a bug. It's part of tetris strategy, so it didn't need to be fixed. I thought it was weird to put effort into changing a fundamental part of tetris in a challenge about making "good enough" tetris...

you should consider implementing matrix in scratch when working with tiles on a set grid in makes things simpler

7:57 Oh wow, that's a funny thing, you're clearly used to programming languages where it will simply crash if you don't have delay at the end of any loop that runs forever, however in Scratch it automatically is capped at 30 fps. Indeed, I believe that you unintentionally made a 15fps game with that wait block.

[@Despatra]

FYI scratch already runs at 30 fps, by adding the wait block you either made it run at 15 or it did nothing

[@XenonNeko]

I did eventually realize this after switching to delta-time later in the project. The delta-time always hovers around 0.03, which is 30 FPS.

[@Z_E_B_O]

never heard the square piece being called o-piece lol. Anyway, really interesting, my idea for the shading would be to have the board, then the tetris fall down on the board and then have an additional third layer with only the shading, so when a tetris enters the board, the shading will always be on top.

Quick question. Why did you not just make each piece its own sprite? I feel like that would end up being all around easier.

[@XenonNeko]

I'm not sure how that would be easier (but that might just be me. I'm not familiar with how things are usually done in Scratch). If you mean splitting the logic into different sprites, I would argue there's a lot of redundancy because the pieces have a lot of common functionality. If you mean making the pieces themselves different sprites, I'm not sure what to do in the case of line clears where pieces can get broken up. And as the board fills up, that sounds like a lot to keep track of. Either way, I find communicating information between sprites to be annoying (again that's just personal preference). If you're referring to something else entirely, please explain.

[@_cfmca]
