@John - think you’re right about the print statements in white. Another funny with the scroll bar in the parameter window, image attached.
@Simeon @John - question a bit out of the box for you:
What information is sent to TLL with error reports?
After mentioning accessing the Codea version from within Codea. I wondered if it would be advantageous if you could supply a package containing the version number, the iOS/iPadOS and the iPad gen info. That way you could pick up on it without having to ask the questions.
Also it could be neat to have an entry on the menu bar list of the Editor to allow users to access the info without having to search for it.
Codea4?A long-awaited new feature!!!
I found two new debug parameter types.
Curve types are sometimes drawn out of the region in parameter.curve().
Test code:
---[=[
function setup()
parameter.color('BackgroundColor', color(64, 64, 64))
parameter.curve('curve', curve(123))
parameter.gradient('gradient', gradient(123))
parameter.vec2("Rotation", vec2(180,0))
scene.main = scene.default3d()
-- scene.main = scene.canvas()
e = scene.main:entity()
e.rotation = quat.eulerAngles(45, 0, 45)
-- e.mesh = mesh.box(vec3(1,1,1),vec3(8,8,8))
-- e.mesh = mesh.sphere(1.3,32,16,0,360,0,180)
e.mesh = mesh.roundedBox(0.25,vec3(1,1,1),2,vec3(8,8,8))
e.mesh = mesh.icoSphere(1,2)
e.mesh = mesh.cone(1.3,1.9,32,8,4,0,180)
e.mesh = mesh.cylinder(1.3,1.9,32,8,4,0,350)
e.mesh = mesh.capsule(1.3,1.9,32,8,4,0,350)
e.mesh = mesh.disk(1.3,0,32,4,0,360)
e.mesh = mesh.torus(0.925,1,16,32,8,4,10,360)
e.mesh = mesh.teapot(8)
e.mesh = mesh.torusKnot(2,3,8,96)
-- print(mesh.texture())
-- e.mesh.texture = mesh.texture(asset.builtin.Blocks.Brick_Red)
myLight = light.spot
green = material.unlit()
green.baseColor = color(228, 21, 9)
green.roughness = 1
e.mesh.material = green
-- Destroy after 1 second when touched
e.touched = function(entity, touch)
if touch.began then entity:destroy(1) end
print(4)
-- scene.editorMode()
end
-- Play hurt sound when destroyed
e.destroyed = function()
sound.play(SOUND_HURT)
end
end
function draw()
e.rotation = quat.eulerAngles(time.elapsed*100, 45, 45)

@Bri_G I am sorry for I made a mistake to cover your bug report item in the google doc, pls rewrite it, thanks.
@binaryblues @Simeon Nice demo. Lot of stuff to look at. For some reason, when I touch the screen the entity:destroy causes Codea to crash. I commented out the e.destroyed code, but it still crashed.
@dave1707 Thank you for your careful examination! I found the same crash. After I tried comment almost every possible line, I got the line who cause crash! It is this line in draw():
e.rotation = quat.eulerAngles(time.elapsed*100, 45, 45)
@binaryblues I added some code to stop the crash. I added “dest=true” and “if not dest”. When the screen is touched, you destroy e but in draw its still trying to do the e.rotation which doesn’t exist anymore.
-- Play hurt sound when destroyed
e.destroyed = function()
dest=true
sound.play(SOUND_HURT)
end
end
function draw()
if not dest then
e.rotation = quat.eulerAngles(time.elapsed*100, 45, 45)
end
@Bri_G error reports usually just give us the time/date it crashed and a symbolcated report if we’re lucky (where it crashed)
I’ll look into what extra debug info we can provide
@binaryblues The new parameter types are still a work in progress (the imgui widgets are a bit dodgy). They can be used with shaders too (I’ll need to make an example project)
@binaryblues @dave1707 When you say crash do you mean it crashes the app or it just throws out errors? You can also use entity.valid to check if an entity is still alive
@john It crashes Codea. Takes you completely out and asks if you want to send a crash report. I’ll try the entity.valid to see how that works.
PS. The entity.valid worked. Can’t wait to get the full documentation that shows all the commands in 4.x .
@John @dave1707 When I say crash, I mean the whole Codea app suddenly quit and went back to the iPad interface. The crash seemed to be a logical problem for my test code: Destroy an object, and then continue referencing it in draw(). It is normally up to the user to avoid this code logic(use a if statement).
The entity.valid took effect.
I will continue to explore new features, very interesting! It seems that our testing schedule occasionally gets ahead of development
@dave1707 You may try to clone the Codea4 help document on GitHub. I’m working on the format and how to submit it so that we can sync up the missing documents as quickly as possible. And there’s a lot of interesting stuff hidden in this document.
In the Physics3D example, I found it support shadow, the default shadow. Sometimes the shadows disappear and are replaced by streaks of light and dark, with varying widths.

@binaryblues What 4.x docs were you referring to on GitHub. This is the one I’ve been looking at. Is there one with more info in it.
https://johntm.github.io/Codea4-Docs/
@dave1707 Looks like another link, but you need to dig into its directory structure to find a lot of interesting test code. After accessing this link, we can assist the developer to update the document and submit it
When I run my project with the new runtime, I get this issue. Is there anything I’m doing wrong/do tabs have to be imported in some way?
If I’m not mistaken, you had a similar issue @skar. Were you able to solve that?
