Debugging Tips You MUST Know as a Godot Developer

[@DucktatorD]

Damn, its actually strange none of the courses I've done so far even mention any of this, the most they tell you about print and printt.

devworm is goated

[@Qas22w]

Nice tips! I want to improve the first one a little bit. You should start the func with "if not OS.is_debug_build(): return" on the first line, and keep all the hotkeys below this. It keeps you from having to write "not OS.is_debug_build()" on every hotkey snippet.

[@dev-worm]

that is a very good point! that would make it much simpler

[@olivermatthews8110]

Also, even when doing it in a single if statement, you should* put the debug check first as it will be ever so slightly more performant due to lazy evaluation. *Strictly you should put conditionals in descending order of probability, but weighted by check cost; so there are times putting debug checks first are wrong, but realistically you can safely ignore them.

although i take break from gamedev and start in appdev i still watch your amazing videos keep up😻

aw thank you so much!! it truly means the world jeremiah!! it always makes me so happy to see your comment!

Thank you, very helpful and we can now make changes to suit.

Im glad I found this when I'm starting to create my game for a jam

that is amazing!! i hope it can help!! goodluck in the game jam!! update me on how it goes!

Thank You for Your video! For Me personally, You chose good selection of things to cover. And i find Your explanations are well between in-depth and to the point.

Glad it was helpful!

I was wondering how I was going to start debugging and understanding various errors that occur. Again, thank you for the tips 🙏

[@completelyrandomlyhandlee]

As always great video! been watching you for some time now and your experience shows. Can i request that you do a video on tile maps and how to delete specific tiles/groups of tiles at a point AND inside and area. You seem to have a good understanding godot and i appreciate how you explain everything.... i have been so stuck and a lot changed with tile maps from 3-4. I KNOW people would watch it.

[@dev-worm]

that is a great suggestion!! i just noted it down and will look into it in more depth soon!! hope i can help!

[@HansMilling]

I hope future versions of Godot will support better debugging. When hitting a breakpoint, it would be so nice to be able to hover over different variables/objects and see their values and properties. Often nothing happens or you just see the objects is. I have not used the print statement since coding on my Commodore 64. So having to revert to that feels so dumb.

[@WizardofWestmarch]

Minor detail but something that could be useful is put the is debug check first so you can short circuit on release. Technically not the biggest deal but a good habit to form in general of putting the thing most likely to end a short circuited if/etc block first to avoid extra binary checks, for those times where it is in an inner loop (and not like doing it makes the code less readable)

[@dev-worm]

that is smart! i don’t know why but i never even thought of that! you learn something new everyday! thanks!

[@WizardofWestmarch]

@@dev-worm Not a problem, thank you for releasing high quality Godot content, we need to keep creating more and more to help everyone who wants to try it :)

[@pennyloafers]

The debug panel and remote tree can do most of this video for you without any code. You can modify values in any node in the scene tree. Although a little more manual and also pausing is a thing. You also have "breakpoint" keyword which wasn't mentioned which can be used for condition breakpoints.

@@dev-worm if you are taking video suggestions. Here are somewhat different of mine: 1. Games made in Godot engine each month top 5-10 2. New Video series about making popular game modes 3. In-depth guides about popular godot nodes. 4. Some stuff you discovered that would save others time.

Really helpful for a beginner

[@dev-worm]

glad to hear!! thanks!

[@DrW1ne]

Best way to debug is to not make bugs in the first place. Sadly that's hard.

[@thesomeone2nd]

More like impossible unless you practice the same project a lot of times.

[@dev-worm]

i wish it wasn’t hard lol

[@hotcrossbun26]

I feel so stupid now for writing code with bugs in it. It was this simple the whole time 😂

[@bloop1504]

hi! im commenting on this because its your most recent video, but i come from your wall jumping and wall slide tutorial! amazing btw, it's been such a great help in my beginning journey as a godot developer! i'm having an issue though, when i first tried your code, i didn't like the fact that the player had the ability to wall jump multiple times on the same wall. so, to try and fix this i implemented code that used rays to check which wall the player was last on and setting if they can jump on the wall to true or blah blah blah, so that they could wall jump between two DIFFerent walls. however, the player is able to exploit this code because they can wall jump on a wall, quickly turn to the other direction, and then quickly turn back to the previous wall and this resets their wall jump, thus letting them jump infinite amount of times on the same wall. is there any way you could try and help me fix this issue? i'm not sure what to do whatsoever, i've thought about adding some kind of cooldown to the wall jump, but i'd rather not because that could stop the player from jumping from two different walls quickly. anyways, your videos have been such a great help to me overall and this is just a tiny issue i have! thank you!!

[@NIGHTMARE-yp4oz]

@@bloop1504 just make it a feature. If you don't want the player to walljump to a place just make it closed. You can checkout hollow knight, it doesn't have any cool down on walljump and has implemented it beautifully

[@MuffinMan_Ken]

is_debug_build will also be true in an exported debug build. There is a separate test to see if you're running in the editor.

[@kunai9809]

0:33 of course there are differences other than that function... Release builds are further optimized than debug builds

[@LocherYT]

i am honestly too lazy to implement proper debugging scripts to set HP or other variables. I usually go straight into the remote tab and tweak thinks around until they look right

can you make a tutorial on how to make enemy ai that con do platforming/jumping/moving

No mention of print_debug()? I know it's a simple one but worth mentioning for a video like this. Or print_stack too which i find to be rarely useful though.

youre right i shouldve mentioned print_debug() I dont know why I didnt! thanks for pointing that out!!

Do you recommend learning gd script for someone new to game development or c#?

debug build is not a very good idea imo. debug mode should be accessible to any player, but hidden away. a lot of games that give the player access to debug mode are also some of the best and most modded games of all time

that is actually a really good point

very nice usage of OS.is_debug_build() !
