-in terms of memory usage- what's the best way of replacing a texture?
i sometimes got an OutOfMemoryError after replacing skybox textures, typically at prewarm stage. if i do removeAndUnload first instead of replacing i end up with white empty textures. i may be doing something wrong with removeAndUnload thing.
unload() doesn't really unloads but schedules for unloading, which happens in the next render. This is a relic from desktop jPCT...it might not be needed for jPCT-AE in most cases. I'll try to add an option for immediate unloading this evening and see if that helps to fight the memory problem.
I've uploaded a new jar here: http://www.jpct.net/jpct-ae/download/tmp/test/jpct_ae.jar (http://www.jpct.net/jpct-ae/download/tmp/test/jpct_ae.jar)
It adds a setting to Config called unloadImmediately. If set to true, unloads will be performed right on calling one of the unload-methods. If this works fine, i'll make it default and remove the setting. Please let me know.
unfortunately i got white textures again..
this is the log in between, in case you wanna see:

??? Are you sure that you have set that Config-setting to true? It's false by default. Please re-download the jar. I've renamed the Config.timingOutput to Config.debugOutput and if true, it will print out some message when unloading the texture.
timingOutput was disabled. still white textures. i set Config.unloadImmediately to true in renderer constructor. unless it's set to false elsewhere in your code (for example when buffer is created) it's set to true.

So unloading seems to happen immediately as planned...but are the new ones actually uploaded? I can't spot any mip-map-generation message in the log. Are you not using it or does it come later or is it simply missing? I've updated the jar again with some upload-debug-messages. Please report the outcome.
right, i don't use mipmaps for skybox. as skybox textures are always at the same distance to camera, it seemed a waste.

Looks fine...it obviously reuses the texture ids, which is a bit strange (never seen that on the desktop) but shouldn't hurt. I'll have a closer look and try to reproduce this problem...
thanks, please let me know if i can help in any way
Can you post a code snippet that shows exactly what you are doing to unload the old and enable the new texture?
sure.
this method is called via GLSurfaceView.queueEvent(Runnable) to make sure it's called in GL thread.
private void changeSkyBox() throws Exception {
Log.v(LOG_TAG, "changing background to: " + background);
TextureBank.unloadSkyBoxTextures(buffer);
MemoryHelper.compact();
TextureBank.loadSkyBoxTextures(glContext, background);
MemoryHelper.compact();
TextureManager.getInstance().preWarm(renderer.buffer);
Log.i(LOG_TAG, "changed background to: " + background);
}
the unloadSkyBoxTextures method:
public static void unloadSkyBoxTextures(FrameBuffer buffer) {
TextureManager tm = TextureManager.getInstance();
if (tm.containsTexture("SB_BACK.JPG")) {
System.out.println("unloading skybox");
tm.removeAndUnload("SB_BACK.JPG", buffer);
tm.removeAndUnload("SB_FRONT.JPG", buffer);
tm.removeAndUnload("SB_LEFT.JPG", buffer);
tm.removeAndUnload("SB_RIGHT.JPG", buffer);
tm.removeAndUnload("SB_BOTTO.JPG", buffer);
tm.removeAndUnload("SB_TOP.JPG", buffer);
}
}
loadSkyBoxTextures method. here context is an interface with desktop and AE implementations. it loads the texture, replaces or adds to TextureManager
public static void loadSkyBoxTextures(Context context, String skyBoxName) throws Exception {
context.loadTexture("SB_BACK.JPG", "/images/skybox/" + skyBoxName + "/sb_back.jpg", Context.ALPHA_DONT_USE, SKYBOX_CREATE_MIPMAP, SKYBOX_COMPRESS, SKYBOX_KEEP_PIXEL_DATA);
context.loadTexture("SB_FRONT.JPG", "/images/skybox/" + skyBoxName + "/sb_front.jpg", Context.ALPHA_DONT_USE, SKYBOX_CREATE_MIPMAP, SKYBOX_COMPRESS, SKYBOX_KEEP_PIXEL_DATA);
context.loadTexture("SB_LEFT.JPG", "/images/skybox/" + skyBoxName + "/sb_left.jpg", Context.ALPHA_DONT_USE, SKYBOX_CREATE_MIPMAP, SKYBOX_COMPRESS, SKYBOX_KEEP_PIXEL_DATA);
context.loadTexture("SB_RIGHT.JPG", "/images/skybox/" + skyBoxName + "/sb_right.jpg", Context.ALPHA_DONT_USE, SKYBOX_CREATE_MIPMAP, SKYBOX_COMPRESS, SKYBOX_KEEP_PIXEL_DATA);
context.loadTexture("SB_BOTTO.JPG", "/images/skybox/" + skyBoxName + "/sb_bottom.jpg", Context.ALPHA_DONT_USE, SKYBOX_CREATE_MIPMAP, SKYBOX_COMPRESS, SKYBOX_KEEP_PIXEL_DATA);
context.loadTexture("SB_TOP.JPG", "/images/skybox/" + skyBoxName + "/sb_top.jpg", Context.ALPHA_DONT_USE, SKYBOX_CREATE_MIPMAP, SKYBOX_COMPRESS, SKYBOX_KEEP_PIXEL_DATA);
}
Now i get it...you can't do the replacement that way... ;) If you assign a texture (directly or by one of the loaders), there's a lookup into the TextureManager for the manager's internal ID for this texture's name, i.e.
"wall" -> 1
"floor" -> 2
etc.
When uploading the texture to the GPU, it gets another ID, the GL-ID, i.e.
1 -> 38
2 -> 39
etc.
When doing on unload() for a texture, the GL-ID becomes invalid and is available for reuse. The TextureManager's internal ID is still valid though. But when doing a removeAndUnload(), both IDs become invalid. However, the object using this texture still refers to the, now invalid, internal TextureManager ID. This causes the textures to go white.
Adding a new texture with same name doesn't help, because it will get a new internal ID (there's no history that knows which ID this name was once used for). I.e:
"wall" -> 13
"floor" -> 14
Possible solution: Don't do a removeAndUnload() but simply an unload(). In the loading-method, only load the textures in the first run and do a replaceTexture(...) afterwards. That should fix the problem.
I would really like to fix this in another way, but i can't keep the references to the texture's names in the object itself...it's just to expensive memory and performance wise. I should document it better though.
Hope this helps.
very well, no problem for me. it works now thanks ;D i've changed skybox a few times and no OutOfMemory yet.
btw, you may want to restrict some more logs to Config.debugOutput too, it's really verbose ;)

I'm actually friend of logging more than i'm a friend of using a debugger... ;) However, i'm open to suggestions. Which log outputs are superfluous in your opinion?
Apart from that, you can turn the log level down in Logger...
ah, ok then. i wasn't aware Logger settings are still valid in AE :)
But maybe i should remove the debug-Setting in Config and add a new log level instead...
Congratulations on your 1000th post btw. You are now officially a "quad".

so i'm verbose too ;D
