[Flash basic theory Lesson 16] Matrix Revolution [double cycle]

Back to "flash Basic Theory Class-Catalog"

In this lesson we will introduce two methods to achieve this effect, focusing on the double loop statement

Also introduce solutions that are not available in the Textfield._alpha method

Single loop:

for (i=0; i < 5; i++) {
　trace("i="+i);
}

The results of the operation are as follows:

i=0
i=1
i=2
i=3
i=4

Double loop:

is to add a for loop in the For loop

for (i) {
　　 for(j) {}
}

Let's look at a double loop example

for (i=0; i < 5; i++) {
　for (j=0; j < 3; j++) {
　 trace("i="+i+" j="+j);
　}
}

The results of the operation are as follows:

i=0 j=0
i=0 j=1
i=0 j=2
i=1 j=0
i=1 j=1
i=1 j=2
i=2 j=0
i=2 j=1
i=2 j=2
i=3 j=0
i=3 j=1
i=3 j=2
i=4 j=0
i=4 j=1
i=4 j=2
i=5 j=0
i=5 j=1
i=5 j=2
i=6 j=0
i=6 j=1
i=6 j=2
i=7 j=0
i=7 j=1
i=7 j=2
i=8 j=0
i=8 j=1
i=8 j=2
i=9 j=0
i=9 j=1
i=9 j=2
