[@limbo9865]

@raffle baffle Yes 😂

[@Mark73]

The radius of your ball is 1. That means the circumference is 6.28 (PI*2). So in rolling 1 unit it will roll across 1/6.28 or 0.159 of its circumference. 360 degrees times 0.159 is 57.2 So for every single unit (which you can measure out with CTRL+drag) it rolls, it will rotate 57.2 degrees.

[@GileadMaerlyn]

35:48 _"I'm not sure why that is"_ I think it's because the *loop* button is activated, so godot knows that at the end it'll be back at the start.

[@karga9589]

You are a great teacher, tutorials were really easy to follow and i've learned a lot. Thanks!

[@wukongmain2075]

fun stuff!, I decided to animate my enemy moving normally around a wall shape i made making a full rotation and then moving backwards a full rotation but at like twice the speed. Might catch the player off guard seeing it come back towards them super fast aha

[@kellywshere]

Great tutorial! By the way: the reason the rotation animation get messed up at first is because at 19:46 you manually rotated the object, which made the z-axis rotation number jump by -360 degrees (from 270 to -90).

[@raidez9987]

Instead of animation, I create a Path node, define path for enemy, put Enemy scene inside a PathFollow node, and use animation player to change the path offset. Make sure to make Path curse property unique and it's working well (much easier to change the path, adjust speed, etc).

[@GaryParkin]

I was going to search for a path and see if Godot had one until I read your reply. Did it work? After the course, I'm going to add AI code to the enemies to wander around randomly and look for the player.

[@Brambi255]

To implement rotation according to movement direction, you can add this script to the enemy node. I'm just a beginner so maybe there's a better way, but it works for me: extends Area var pos var currentPos var deltaPos const ROTSPEED = 100 func _ready(): pos = global_transform.origin func _process(delta): currentPos = global_transform.origin deltaPos = currentPos - pos rotate_x(-deltaPos.z * ROTSPEED * delta) rotate_z(deltaPos.x * ROTSPEED * delta) pos = global_transform.origin

[@TechBoxNorth]

Wouldn't it be better if Steve (the player) was the one checking for collisions to reduce the number of collision checks?

[@sergeantsapient]

I think he mentioned something about areas being good at detecting collisions with physics bodies. Maybe he meant they're more efficient than physics bodies. Best I can reason. Maybe it's something to do with that areas calculate collisions every frame faster because they're not calculating physics like the physics bodies would be.

[@HarryRasmussen]

Great lesson. Thanks!

[@mjdragon13]

For those trying this out in Godot 3.4.4, area_entered might not work! Try the body_entered function to do the enemy player collision but with the same code! Thanks for the wonderful tutorial @BornCG

[@Phrate]

area_entered checks if it has a collision with other "area" type nodes, which our Steve is not. Steve is a kinematic/physics body, so body_entered is the correct choice

[@dejo095]

If anybody is asking how he created that spiked ball, Im guessing he subdivided the cube, applied the modifier. Then he selected all faces, inseted them, as each face for itself, then extrude-scale them then subdivision modifier in the end :-)

[@josemayorquin6911]

My enemy imported in the sky, so I put him on the floor and added the keyframes. But when I hit play he appears out in the ocean

[@fhajji]

@BornCG: The enemy looks like a Coronavirus. Which brings me to an idea of an epidemic simulation game: - Change the enemy in Blender to look more like Coronavirus - If Steve collides with an enemy, change state of Steve to "incubating" - After some time, change state of Steve to "active", and have it "cough", creating new enemies (viruses) - If Steve touches walls, mark them as "contaminated" as well - Now, add more players (multiplayer-game in Godot? Is that even possible?) in the scene and have them dodge the viruses. - In the players collide with viruses, or contaminated walls, mark them as "incubating" - Every player that hits more than a set limit of enemies (viruses) will then die... or have them die according to a preset mortality rate - Have the enemies die after some time, just like the real viruses which become inactive after a while. - Optionally: spread some "disinfectants" in the maze, so that player that collided with walls not too long ago can avoid getting to the "incubating" stage if the hit a disinfectant, a.k.a. if they wash their hands. That would be a great continuation of this series. As always, excellent tutorial! Love it!

[@RonicTheEgg]

how dare you be so awesome

[@BornCG]

🤣😊

[@Wilker_uwu]

the issue of the rotation animation is that you changed one of the keyframes, but when you set up the frames before changing, you stored the first value in all of them. you rotated 270 degrees in the second keyframe, but all the others were still zero, because that was the value which you set when creating the frames before animating. so the values were like 0 to 270, then back to 0.

[@Wilker_uwu]

i know the video is old and you might have already known :p that's just to help people coming here who happens to browse by new comments ^^

For fun: what if you turn the enemies a cube and made them roll like a dice? How you would change on code to make them behave like that? BTW, thanks for this tutorial. You make it seems easy to code a game with all your examples. Any chance of allowing subtiles and translations? I would like to do them to my native language. You know, good will of helping others reach the same content without language boundaries limiting them.

[@eidanyoson7898]

Im using Godot version 3.2.3 and following step by step (great tutorial by the way!). Ive noticed that when I press the play scene button, the game takes dramatically more time to load in comparison of what I see on the video. Is there some sort of performance configuration in project settings to gain speed or is it the version difference? Im using a geforce gtx 1060 by the way

[@iakobs]

HI! If you look at the chapter adding the walls (it's 5 IIRC), you have the problem and the solution in the coments. TL;DR godot is buggy when it comes to make materials unique, it's much better to duplicate them

[@Phrate]

@@iakobs It's not a buggy thing, it's basically asking Godot to throw out its efficiency. Instead of just one reference to the mesh and material, it's now storing a couple hundred new copies of the 7mb mesh and 2k texture. Then it's building and rendering every single one of those over and over again from scratch. Make Unique is very powerful and it was most certainly used completely wrong in this tutorial. Nonetheless, was an awesome tutorial!

Isn't there a calculation you could do to auto roll the ball based on its position? I looked at this but I could not find a way for the enemy ball to know its moving. (Newbe)

[@llYuki0okami]

enable Autoplay and Loop in animation options for enemy 2

[@koto3015]

@@llYuki0okami thank you, i was so confused

[@Galaxia53]

When I tried to make the enemy take a corner twice the y axis started to turn on the z axis making it seemingly literally impossible to make him roll on the y axis again. The Y rotation takes the Y axis from the environment while the Z takes the one from the enemy. This animation system is the worst thing ever. Edit: I found a better way to do it. Copy an enemy and remove it's animation node. Basically you get a "Path" node then you get a few extra options at the top middle of your screen, select the second option with the little plus sign in it and now you can draw a path (best done in top down view). You can close the path with the fourth option next to "options". Now add a "Path Follow" node as a child of the "Path" node and make the enemy a child of the "Path Follow" node. Make sure the enemy is located at the exact point the path begins otherwise it's gonna look really weird. Now click on the "Path Follow" node and on the right there is an option called "Rotation Mode" which is on XYZ, put that on "Oriented" so the enemy will face the direction the path travels. Then just animate the enemy rolling (so not it's position) and face the enemy the way the path goes which is the direction you drew the path. You can also see how it will look by clicking on the Path node and on the right of the screen is an option called "Offset". Now add this piece of code to the "Path Follow" node which I can't exactly explain (sorry): "extends PathFollow var runSpeed = 5 func _process(delta: float) -> void: set_offset(get_offset() + runSpeed * delta)" Now it should work. You can even smooth out the corners it takes a bit by clicking on Path, on the right of the screen click on "Curve3D" then increase the number of "Bake Interval" a bit.

[@carterazilla5216]

it doesnt print hit? help

[@andrewalekseyev2460]

Can you please help!!! For some reason after doing two keyframes of the animation and having everything work just fine the z axis completely stops working. If you try to change it it just rotates the ball on the same axis as the y axis and it is no longer possible to to rotate the enemy on the z axis no matter what I try. If I try just manual turning it in the editor and use that as the keyframe it just switches ALL of the axses to something like -90 or 180. I have looked online but I haven't found anything

[@Galaxia53]

For me it screwed up the y and z axis when I tried to make the enemy take two turns. If you also tried to do that then I can say that that doesn't work at least with the method in this video. If I make the enemy take one turn it works for me. Right now I use Godot 3.5 but it screwing up the axis was in a version before this. If you didn't try to do something different from the video then you may want to try and redo the animation completely and try to do exactly what he does. You may have done something different or wrong by accident thus not understanding why it's not working.

[@schnitzelhannes6431]

simple enemy script for doing the rotation without the AnimationPlayer: var origin = Vector3(0,0,0) const ROTSPEED = 5 func _ready(): origin = translation func _physics_process(delta): if (translation.x > origin.x): $enemyMesh.rotate_z(deg2rad(-ROTSPEED)) if (translation.x < origin.x): $enemyMesh.rotate_z(deg2rad(ROTSPEED)) if (translation.z > origin.z): $enemyMesh.rotate_x(deg2rad(ROTSPEED)) if (translation.z < origin.z): $enemyMesh.rotate_x(deg2rad(-ROTSPEED)) origin = translation

Super crazy busy this week running a 3D printing camp. The good news is that #8 is already recorded, but needs editing.

[@sergeantsapient]

Years later from the tutorial but I think I understand why it's changing the z axis. It's because it's trying to return back to the original value that it was keyed to in the beginning by the time it gets to the end of the loop. This is expected but rather annoying behavior XD.

For the life of me, I couldn't get the enemy ball to roll without spinning uncontrollably in undesired directions. Godot 3.4.4

[@Galaxia53]

I had the same problem but I finally did come up with a solution. What it does is when it's done rolling ones it wants to roll back to it's original position (before it started rolling) while at the same time it rolls towards the point you set next. So if I want it to roll to 100.x and then want it to roll to 100.y it rolls to 0.x 100.y and it wanting to roll back to 0.x is what's causing it to roll weird. The solution is a little odd but it works well. If the first diamond encounter is 100.x then the diamond after that should be 100.x 100.z in order to make it roll to the way you had in mind when you typed out 100.y Just to make a damn ball roll lol.
