JHCR setup with Wurst

[rosen]

Hello Hive Workshop, first-time poster here.

I recently got back to wc3 map making and found out about Wurst, which made me really happy. I've managed to set up the starting project and can edit a few things. However, I cannot get hot reloading to work with JHCR. I've followed the Wurst hot reloading guide over here: WurstScript • Hot Code Reload Guide.

When running the game from VSCode using the "Run a Wurst map with Jass Hot Code Reload (JHCR)", adding another print statement in the init method of my one package, updating the code with "Reload code for a Wurst map start with Jass Hot Code Reload (JHCR)", and finally hitting Esc in the game, all I get is "Code reloaded!" in the chat, but not my new, nor old print statements.

Have I completely misunderstood the purpose/usage of JHCR or is something weird going on?

Thanks in advance!

Sincerely, a beginner.

It would help if you posted the code before and after you reloaded it.

Before

wurst/Hello.wurst

package Hello

init
    print("Hello")

and after

wurst/Hello.wurst

package Hello

init
    print("Hello")
    print("World")

Before

wurst/Hello.wurst

package Hello

init
    print("Hello")

and after

wurst/Hello.wurst

package Hello

init
    print("Hello")
    print("World")

Well init is never executed again, so it's reasonable that nothing is printed.

Thanks, that's what I suspected. What code could be hot reloaded? Code that's run on certain actions?

Yeah trigger actions or periodic code.

So I tried the following, but still can't get it to work. It's probably just me who's not getting the hang of it, so I appreciate the help.

Before

package Hello

import DamageDetection
import UnitIds

init
    createUnit(localPlayer, UnitIds.archer, vec2(100, 100), angle(0))
    addOnDamageFunc() ->
        custom_func()

function custom_func()
    print("Damage Event with dmg: " + GetEventDamage().toString())

After

package Hello

import DamageDetection
import UnitIds

init
    createUnit(localPlayer, UnitIds.archer, vec2(100, 100), angle(0))
    addOnDamageFunc() ->
        custom_func()

function custom_func()
    print("Damage Event with dmg: " + GetEventDamage().toString())        
    print("Hey")

The on damage message does not appear to be updated. I tried the same with

init
    doPeriodically(0.5) cb ->
        print("Something")

But changing the print message didn't change anything either

It *should* work Guess i will have to investigate, maybe on the weekend.

I have updated jhcr. It should work now after you re-downloaded jhcr.

Amazing, now it works!

One more question, I read in the beginner guide that there is the .jurst extension as well, which is for curly bracket syntax? However, I cannot find any information on this in the manual or anywhere else. Is this discontinued or just lacking documentation? Coming from languages that use this kind of syntax, which I myself prefer, it'd be pretty nice if it already existed

No, you misread. The jurst syntax is more closely related to Jass, using verbose keywords to end blocks.
If you are used to curly braces, wurst is super easy: just leave them out! It should be the only difference.
