Counting Sprites
Материал из Поле цифровой дидактики
Шаблон:April FoolsIf you have a lot of clones with a local variable, they may want to count them automatically, rather than individually assigning each of them a number in a set () to () block. With this method, a script could specifically call the number-seven clone without hard-coding it.
Method
Firstly, a global variable (sprite count)
should be created. Then, on the stage, the following script should be added:
when gf clicked set [sprite count v] to [0] broadcast (count sprites v) and wait . . .
Now, for all the sprites that want to be counted (and generally these will be clones of the same sprite), this script should be added:
when I receive [count sprites v] change [sprite count v] by (1) // This takes advantage of the fact that scripts are not run at the same time. set [my number v] to (sprite count) // Swap these two blocks to start count at 0 instead of 1
Then, when the flag is clicked, each sprite will obtain a unique number in (my number)
.
This works because of the execution order of broadcasts.
