What does this error mean

For-loops in java must always have three parts within the parentheses, delimited with semicolons. You can leave any of the parts blank, but you need to include the semicolon separators. You for-loop only has one semicolon between the parenthses

[carmine loom]

would putting a semicolon and i=i have the same effect?

[sour pebble]

yes

for (int i = 0; i < 14;) {

}

would do the same as

for (int i = 0; i < 14; i=i) {

}

since well, i=i doesn't do anything

[carmine loom]

sadge it doesn't work

🙁

[sour pebble]

well thats a logic problem, no?

[carmine loom]

probably but I don't get it

[sour pebble]

the problem here is that you ask

"is the front clear"

if yes, go forward

if no...?

just does nothing

then

while the front is blocked - turn left, move forward, turn right move forward, ...

but thats not really general directions

[carmine loom]

the thingy I'm using has those things given (suppose the library has those methods)

[sour pebble]

yeah no i get that

i'm saying that those directions don't work when you get to the end

try this

if (frontIsClear()) {
    move();
    i++;
    continue;
}
if (frontIsBlocked()) {
    jumpHurdle();
    i++;
    continue;
}

what I think is happening (and to be clear i'm not reading too closely)

is that you know you need to go 14 spaces total

and you either go forwards or "hop", which is a bunch of small steps

but because you say "while front is clear"

and "while front is blocked"

you are making more than 14 moves

and so are just reaching the end and trying to hop over the last wall

[carmine loom]

Shouldn't turning i<13 limit it to the block before the last block? Then, I should be able to just say move(); that doesn't work for some reason

[sour pebble]

it would, if you only did one thing for each i

[carmine loom]

one block for each i?

I feel like I'm doing dat tho since I place one "jumpHurdle" and one block

[sour pebble]

public void run() {
    for (int i = 0; i < 14; i++) {
        if (frontIsClear()) {
            move();
        }
        else {
            jumpHurdle();
        }
    }
}

try this^

[sour pebble]

after while (frontIsClear()) you then execute while (frontIsBlocked() before checking if you've done 14 things total yet

[carmine loom]

it worked with i<13 for some reason

[carmine loom]

doesn't make a lot of sense but as long as it works ig

[sour pebble]

well lets not move on until it makes sense

if you have 14 spaces to go and you start in one of those spaces

well thats only 13 to go

[carmine loom]

oh truee

ok, I get it thx

.close
