![SPD: check if showing before show [not Scratch 3]](https://cdn2.scratch.mit.edu/get_image/project/85198054_480x360.png)
*** NOTE: was for Scratch2, not relevant in Scratch3 *** ======================================== About time we had another one of these... This one demonsrates that using a "show" block does take a little time - it's slightly better to have a variable to check if you're already showing, rather than always just doing the "show". However, note that I had to make it show *fifty* times per frame in order for it to have a really significant impact. That means this is only something you'll want to bother with if you need to scrape out every last bit of performance to avoid lag. But see happens when you add a speech bubble: https://scratch.mit.edu/projects/85236326/ One interesting thing to note: the same is NOT true of "hide"... It's better to always just hide rather than check if already hidden. (But the difference is really even more marginal in that case!)
