We are Wilber, prepare to be assimilated …

The picture below must look strange to you: A poor sod being looked upon a group of billboard-carrying Wilber aficionados.

So many Wilbers ...

Like all tutorials gone wild, I had some fun improvising on the Blueprint tutorials from the Unreal Team. The example here is focused on mass-producing a series of attributes and behaviour into one object – a Blueprint – and then drop as many as I want into the scene.

So here we see the famous UE4 Blue Man in idle position.  Around him is a capsule that prevents the player to go through him and an additional box that is used as a trigger when my player enters his “personal space”.  Once in it, I can then use some key to trigger an interaction between me and the character.

Blue Man, capsule, trigger and billboard.

The ‘Wilber’ (the GIMP’s mascot) on top of the head was a funny thing.  It’s my first try in billboards and I’m currently using the one that’s built-in the characters blueprint.  I originally wanted to write names and professions over each character’s head when I figured that dealing fonts and transparencies isn’t that easy. So I went with something simpler, like having this iconic mascot with transparent contours. I happy with the “always-facing” part but it needs to be less geographically located on the Z axis (or whatever axis that may be since UE4 uses Z for “up”).

I still have issues with it.  Unreal fails to load a 32-bits PNG file with transparency into the asset editor directly.  So I got the simple DirectX texture tool, loaded the PNG into it then saved it as a A8R8G8B8 format.  When I load it, the texture is now considered as a DXT5 file but it still kept it’s alpha channel.  I finally got transparency when I took the alpha channel and connected it to the opacity property with a translucent blend mode.  I’m not sure if this is the best way but it will suffice for the moment.

The immigrant list

Fork me on GitHubI had some fun with a list that crossed my social media sphere.  It’s basically a rant against anti-immigration types that points to many “foreign” goods they might consume everyday.

While it’s very PC and OK to share, it didn’t stop me from picking it up and play around with it … for science.

Android-x86 inception

I tried to familiarize myself (again) with Android development.  I found the virtual devices in Eclipse … well … not performing enough.  So I tried using the Android-x86 project into VirtualBox box and it worked well.  And I couldn’t resist seeing my own web site through the eyes of my new “device”, running the Emscipten code from my previous post flawlessly.
