*) EDIT: This has been solved -see last post.
Off topic: Would be nice if we could change or at least add to the topic title something like [SOLVED] or [WORKAROUND FOUND]..

Hi,

I've stumbled onto something puzzeling.. Before I could have 2 animated characters displaying shadows without any issues in Win 10 x64. See pics below:

(code+media can be downloaded here: http://www.mediafire.com/file/55whby55hsv1dj1/CharacterController_Ragdoll3.rar )


Now, in AppGameKit-V2017.09.25-Windows, it somehow messes up the shadows of the 2 animated characters see below:


Anybody has an idea what's going on? Is this a new bug caused by the latest changes? Can anybody confirm it's the same for them?

[EDIT]
To make it more clear: as soon as I add the 2nd animated character's shadows, then the shadows of both animated characters get mixed up and they are no longer stuck to the individual characters and do no move along with them. So when I move the player it's shadow doesn't follow him around but remains in the same area and looks distorted, mixed up with the other characters shadow..
BTW: I've now tested under Android too and it's the same there.

Ok.. Found out I had to go back 2 versions(V2017.08.16) for it to work properly again...

So definitely a bug I'd say. Especially as fails on both Windows 10 *and* Android 7.01.



(BTW: Would be nice if we could also edit the subject title of threads for the question mark can now be removed.)

Thanks, fixed for the next version. It was caused by the second animated object having more bones than the first. You could work around it by loading the object with the most bones first, then the other animated objects.

@Paul Johnston:
That's very good to hear. Many thanks for checking this.
I'll try the work around for now.

@Rick Nasher:
how did you multiply the texture on the floor?
I watched your code sample. I understood how to do the shadows.
But it's unclear why you have the texture multiplied completely, but I only have 2 strips to the right and forward. and that's all.
thanks in advance.

Try to resize your texture as a square texture (it seems rectangular no ?) (power of 2 as janbo said further

How about SetImageWrapU(ImageID,1) ?
And check if the image is a power of 2 so it works on all platforms.

Well, I can't take all the credit as not all of that code is 'mine'. I actually took the charactercontroller code from here https://forum.thegamecreators.com/thread/216683 , fiddled a little bit with it and added some stuff as a quick test to see how animation, shadows and physics would go together performance wise.
It was doing quite nicely as you can see.

I needed the floor to be larger and scaled it up a bit. When I did, I stumbled upon the floor tile stuff being a bit odd, getting stretched weirdly, so I 'fixed' it, can't remember how really though, is already a little while back and am quite busy doing something without textures and I tend to forget quickly when not using things for a while.

Original code:


My scaled up code:


Check:
Quote: "
SetImageWrapU

Description:
Sets the UV wrap mode of the image when the U coordinate goes outside the range 0-1. The default is mode 0 which clamps the pixel value to the last valid pixel, mode 1 repeats the texture starting from the opposite side.

To use UV values outside 0-1 successfully on all platforms the image in question must be a power of 2 in width and height, and not be part of an atlas texture. This applies to both clamp and repeat.
"


And:

Quote: "
SetObjectUVScale

Description:
Modifies all meshes in the object to use the specified UV scale, see SetObjectMeshUVScale for more information.

@janbo

BTW: love your environment mapping video


Was already wondering how to do mirrors in AppGameKit, for in Blitz3d it was quite clear how to do reflective surfaces, mirrors and cube/sphere mapping.

Bug fixed in the version latest version 2017.12.12 :

Quote: "•Fixed animated objects causing incorrect shadows if an object with more bones was loaded after an object with less bones"


Many thanks Paul Johnston & AppGameKit team!
