i've noticed gmedia in all plugins folder. it does not contain the windows dll's though.

simwhi · April 2015

I've installed the latest version of Gideros so that I could update the volume control issue with our app. Unfortunately, none of the graphics are displayed after building a debug or release version. I'm not sure, but I think the images are positioned off screen for some reason. We do get ads and the sounds work.

I haven't made any changes to my Gideros project. Am I missing something?

hgy29 · April 2015

Hi @simwhi and others, this new version include significant change in gideros core graphics: a switch from OpenGL ES 1.1 to 2.0 version. That is to say that this version should be considered as a beta or tech preview. If you experience unexpected graphics issues, please report os version and device model so that we can check for specific issues on these devices.
It is probably not safe yet to distributes apps exported with this release until it is fully stable.

keszegh · April 2015

a bug:
the gideros editor is again hanging up regularly, like it did in the past at some point. usually i use zbrane, so it does not matter much, but the problem is there.

question:
how can we turn off perspective in 3d, i.e. make the 3d space axonometric?

hgy29 · April 2015

@keszegh, as of today we only handle perspective projection and orthogonal projection, the latter being the default if perspective is not configured (no sprite size reduction if they are far away).

I guess it may be possible to make axonometric projection in a future version with an appropriate projection matrix. I am more concerned about bugs like @simwhi 's one for now

hgy29 · April 2015

Following my previous post regarding graphics issues, if like @simwhi, one doesn't get any display (let aside plugins), it would be very useful for us to get logcat dump or xcode console dump, which may display important information about the issue.

SinisterSoft · April 2015

It maybe that he had to change the manifest to the ogl setting?

@simwhi If you create a blank project and export it to eclipse then you will see the new manifest and if there are changes you need to make.

ar2rsawseen · April 2015

yes @simwhi try clean export

keszegh · April 2015

@hgy29, i was meaning orthogonal (i don't know what's the difference between orthogonal and axonometric, even after checking a bit on wikipedia) i think. so not setting the frustum or setting to 0 should give orthogonal projection. in the example projects (3d cube e.g.) by not setting frustum or setting it to 0 we don't see anything on screen. btw, setting it to 1 gives an 'almost orthogonal' projection, but probably it should work with 0, right? am i missing something?

MikeHart · April 2015

The player now crashes right at the start on OSX. Where do I post the bug again?

MobAmuse · April 2015

All good on mac for me - love the 3d stuff.

hgy29 · April 2015

@SinisterSoft and @ar2rsawseen: good point a clean export is a prerequisite.

@keszegh, there is an undocumented fact about orthogonal projection in that it only renders sprites which have a Z below 1 (between -1 and 1 to be more precise). This is how it was done in 2D only and I didn't thought it would be useful to use ortho projection for something else than pure 2D. Of course these clipping values could be changed later, they won't affect 2D at all.

keszegh · April 2015

would be useful to be able to change those clipping values. orthogonal projection is good for flipping cards, isometric view, etc.

hgy29 · April 2015

I'll integrate this for the next release. The second parameter to configureFrustum could be used also in ortho projection

hgy29 · April 2015

@MikeHart, I think the best place to report a bug is on github issues list

MikeHart · April 2015

Ok @hgy29, posted inside issues section on Github.

ar2rsawseen · April 2015

@hgy29 @MikeHart seems to be a shader issue, maybe GL2 not supported?

MikeHart · April 2015

Could be. If that was changed, then most likely my machine isn't compatible with Gideros anymore.

hgy29 · April 2015

@MikeHart, it shouldn't have crashed no matter it is a GL2 incompat or not. A suspect more an unusual behavior of your GL driver. I'am adding more safety checks in the gideros code to avoid some issues...

tkhnoman · April 2015

@hgy29 Thanks for the 3D, it looks so great on my game

Regarding png tranparency, can it be treated as invisible and we can see the object behind it?

tkhnoman · April 2015

This is the result, before and after
(This game already gone from mobile market and being prepared for PC)

Somehow the Alpha of png bothering me right now, for example for the spikes and particles.
But if it can't be treated as invisible, then i guess i need to do a little work for shaping each of them

Really great job, thanks for this great stuff. ^:)^ ^:)^ ^:)^ ^:)^ ^:)^ ^:)^

Quite good

How have you added the perspective effect in the tiles?

Just using application:configureFrustum and setZ for the Sprites? I am really interested to know about it.

hgy29 · April 2015

Wow @tkhnoman, you weren't long taking benefits from 3D stuff, I am happy you found it useful. As for transparency, it should work as before provided you don't wrap them in 3D meshes. I think the issue you have is due to depth test, which prevent GL to draw a sprite if something nearer as already been drawn at that place. But depth testing is only enabled in 3D meshes and their childs, so you could rework your scene to avoid this artifacts I think.
BTW should I include an option to disable depth testing ?

hgy29 · April 2015

While I'm at it, another trick that could be used is to displace your 3D mesh slightly along Z (say 0.001) and still place your spikes at Z=0, so that the spikes are always in front of the tiles. I used something like this in the dice demo: the dots are not exactly on the dice face, but a fraction above. Not noticeable but does the trick for openGL.

ar2rsawseen · April 2015

@tkhnoman we want a video

SinisterSoft · April 2015

@hgy29 I think that there is a problem with the transparency in 3D - transparent pixels shouldn't be drawn - but they also shouldn't affect depth. I that is what has happened here - the transparent pixels are bring up the background to their level, even though they are invisible.

SinisterSoft · April 2015

Here is a pdf that tells you what needs to be updated in the activity:
http://www.sinistersoft.com/downloads/UpdateActivity.pdf

Here is a utility that will update the libs and manifest:
http://www.sinistersoft.com/downloads/UpdateProject.exe

After updating the libs, export (you only need to export the file, not a clean export) your project then follow the UpdateActivity pdf.

keszegh · April 2015

@SinisterSoft, this is not needed in case of a clean export, right?

SinisterSoft · April 2015

No, it's not if you do a clean export. It's just a little util for people who would rather not do a clean export - like me.
