Code wont jump to 'label'

[Tandem]

In the level "spacial invasion" I use the following code, but it never jumps back to the labels and instead runs through all the blank bytes in memory before restarting. What am I missing?

#Opcodes
const reg0_to_out 0b10000110
const in_to_reg3  0b10110011
const if_zero     0b11000001
const always      0b11000100

const up    1
const wait  3
const shoot 5

shoot reg0_to_out

up reg0_to_out
   reg0_to_out
   reg0_to_out
   reg0_to_out
   reg0_to_out

label checkForRats
  in_to_reg3
  doNothing if_zero
    shoot reg0_to_out
    checkForRats always
label doNothing
    wait reg0_to_out
    checkForRats always

Your code certainly looks like it should loop back.

So maybe your condition component doesn't handle the "always" condition correctly?

To debug it, set a breakpoint at one (or both) of the "checkForRats always" lines (click at the very beginning of the line and a red dot should appear), then click Run / F6 and it will run up to that line and pause there.

As it will have paused on the register loading with the label value (i.e. on "checkForRats"), click Next / F5 once so it advances forward to the "always" branch instruction.

(alternatively, you could also move your "always" instruction onto a separate line; that way you could set a breakpoint directly at the "always")

In that state, check the output of your condition component. It ought to output a 1 / On. It's possible that it doesn't, which would mean it ignores the branch.

If it is indeed 1 / On, though, it might be that your branching circuitry fails to load a new value into the counter in another way. So also check that your Counter's "Overwrite" input receives a 1 / On signal.

yep my condition component turned out to be the culprit. Thanks for the help!

My pleasure

I also played around a bit with "The Lab" (don't remember when it unlocks), but I only came up with a convoluted way to test jumps/branches and wasn't able to use expect with the program counter. So I guess the usefulness of "The Lab" for testing jumps and branches is currently limited.
