Sqi:Kuba

Blocks (Kuba) janë pjese-pazëlli formate që përdoren për të koduar në Scratch. Kubat lidhen me njëri-tjetrin si një pazëll, ku çdo  kategori e te dhënave (ngjarja, urdhëri, te dhenat e reportuara, te dhenat Vertete/False, ose mbarimi) ka formen e vete te vecante  dhe nje vend me forme te vecante ku mund te vendoset  kjo parandalon gabimet gramatikore. Serite e kubave te lidhura quhen scripts.

Ekzistojne 12 kategori te kubave: Levizje, Shikon, Audio, Stilolaps, Ndryshyeshme, List, Ngjarje, Kontroll, Ndjeshmeri, Operatore, PicoBoard, edhe LEGO WeDo (megjithate jane dhe kategori dhe kuba te tjer ne Scratch modifications). Vetëm 10 janë në Block Palette.

Në total, janë 11 kuba kapele, 5 kuba C, 37 kuba reportues, 13 kuba Vertete/False, 2 kuba kapake dhe 77 kuba ndertimi. Sqi/Category:Project Items

Forma Kubesh
Ekzistojne 6 forma te ndryshme te kubavet: Kapele, ndertimi, Vertete/False, Reporter, C and kapake.

Kuba kapele


Kuba kapele eshte kubi qe fillon cdo tregim. Ato kane form me nje rreth ne anen e siperme dhe nje nyje ne anen e poshtme kjo forma eshte qe te vendosesh kuba te tyere vetem nen to. Jane 11 Kuba kapele, 6 nga te cilat jane ne kategorine Ngjarje, 1 ne kategorine Kontrol, dhe 4 me shume kuba kapele. Disa shembuj te kubave kapele jane: when gf clicked, ose when this sprite clicked

Stack blocks


Kubat e ndertimit jane kubat qe zbatojne komandat kryesore. Ato kane forme me nje te prere ne anen e siperme dhe nje nyje ne pjesen e poshtme keshtu qe mund te vendosesh kuba siper dhe poshte tyre. Ekzistojne 77 kuba ndertimi forma me e perdorur.

Boolean blocks


Boolean blocks jane kushtezues ato jane e vertete ose false. Eshte njesoj sikur te pyesesh shokun tend: "Eshte 2 + 2 = 4?", dhe ai do te te thote "YPo" ose "Jo". Me nje forme 6-kendeshi, jane 13 kuba te tille.

Reporter blocks


Kubat reportere jane vlerat. Kubat reportere mbajne numrat dhe shirit. Eshte njesoj sikur te pyeseh shokun tend, per shembull, "Sa bejne 2 + 2?", dhe ai do te pergjigjet "4". Nuk eshte vetem ekuacion, mund te raportoje te ndryshueshmet, per shembull, "Sa vjec je?". Ai mund te pergjigjet: "15". Me ane te rrumbullakta, ka 37 kuba te tille pa numeruar sasine teorikisht te pafundshme te kubave reportere qe mund te behen per cdo vlere te ndryshueshme dhe liste. ---(Partially) Translated up to here---

C blocks


C blocks are blocks that take the shape of "C's". Also known as "Wrap blocks", these blocks loop the blocks within the Cs or check if a condition is true. There are five C blocks, and they can be found in the Control category. C blocks can be bumped at the bottom, or capped.

Editing the Block Colors


In the online Scratch 2.0 editor, by shift-clicking the Edit menu an option called "Edit block colors" appears. By selecting this, a menu will appears with a few color sliders and tools for modifying the block colors of a specific block category. Personalized colors can be saved to one's computer, but loading the colors currently does not work properly.

In Other Programming Languages
Scratch is one of the original languages ever to use blocks, inspiring other languages to inherit the idea. Scratch modifications contain many new blocks typically that are not present in Scratch. MIT, at which Scratch is designed, has also created other languages using blocks such as the MIT App Inventor. Stencyl is a highly-professional language that features an entire block interface for programming real-time apps and online games. Scratch Jr also has blocks which are even more friendly for younger children to understand.
