EOS If clause question

[sirveillance]

Hello EOS Developers.

I want to show an image from a gallery, with different galleries to chose from. the shall have different propabilites to be chosen.

so i generate a random number between 1 and 10 in an eval:

Code: Select all

n = Math.floor((Math.random() * 10) + 1)

then i have a switch for that in an eval:

Code: Select all

switch(n) {   
case 1: 
case 2: 
case 3: str = 10; strokes = strokes + 10; break;
case 4: str = 15; strokes = strokes + 15; break;
case 5:
case 6:
case 7: str = 20; strokes = strokes + 20; break;
case 8:
case 9:  str = 25; strokes = strokes + 25; break;
case 10: str = 50; strokes = strokes + 50; break; 
default: str = 1; strokes = strokes + 1;
} 

which basically sets str to a number for a category and adds to the stroke counter.
up to here everything works well.

Next, i use the IF Clause in EOS.

IF:

Code: Select all

str = 50

Actions:
Show a random image from gallery number 50
Goto next page

IF

Code: Select all

str = 25

Actions:
Show a random image from gallery number 25
goto next page

.... and so on.

The variables work as they should. But the images don't.

I have 5 IF clauses on the page but always the last image from the last clause is shown, even if variable STR is not matching the IF sentence.



Any Ideas what i do wrong?

Most of your other code went over my head since I am very new to java. However, from past experience I've found that when using If statements you need to use 3 equals signs (maybe 2 works as well). If you use 1 equals sign, the if statement will act as an eval and change your variable. Try it out for yourself:

EVAL:

Code: Select all

A = 0

SAY: A = <A>
(says "A = 0")

IF:

Code: Select all

A = 1

ACTION: GOTO page 1
(goes to page 1)

SAY: A = <A>
(says "A = 1")

The second SAY will show that the variable A has been changed by the IF statement from 0 to 1. However, if the IF statement was:

Code: Select all

A === 1

the variable will remain 0 and your code will work as intended. Hopefully this makes sense/helps!

aw. you are right. i have no experience with javascript, so that caught me offguard.

for the record:

equal to is ==
euqal to and same type is ===
not equal to is !=
not equal to and not the same type is !==

Interesting, thanks for the info! Does a regular = mean anything special?

[sirveillance]

it is used to set a value, as in
variable = 1 // which sets variable to one.
