P.S.

If you did find the time to upload that optimised Jar I'd really appreciate it! So I could let you know if it does make a difference on performance on low end devices such as mine...


And Number 2: how do you handle animations and variable frame rate? Do you always advance the animation by a fixed increment regardless or do you modify it with the delta time? I'm guessing that both ways there will always be a bit of stutter.....

Thanks very much for your time Egon!

Hi Egon

Sorry to re open this, but I am having the same issue. That's most likely due to the phone I am using for development which is quite low end (600 Mhz CPU, 256 MB RAM, v2.1) but basically when activating the Elipsoid collision detection the frame rate drops from 30FPS to 18-20...

The model I am using is roughly 1800 vertices with 4 frames of animation, and the world has got around 20 models, all very low poly, only 5-10 of which are set to collision_check_others (I too noticed that reducing the amount of these or simply the amount of visible objects makes quite a difference)... and the recursion depth I am using is only 1. The objects are all stripped loaded from serialized files....

Is there any other step I could try to improve the framerate while maintaining the ellipsoid collision?

Thanks a lot

Thanks Egon

In your exeprience, does the use of sound effects impact performance greatly? If you think of a lower end device....

Hi Egon

I am not sure if this is a bug or whether I am doing something wrong. So I'd like to have an option in my program to reset all of the object's transformations. clearRotation and clearTranslation are already there, for the scale however there's no such option. Through testing I realised that the only way to get the object back to its original size is by calling setScale(0). By after that if you call .getScale() you still get the incremented scale value from before resetting.

So basically:

obj.scale(2f);
obj.setScale(0);
float s = obj.getScale()

would return 2, whereas I'd like it to be back to 1 so that when parsing the object information the object is not scaled incorrectly?

Thank you

If you are using blender this page is your friend:

http://bitchesandcastles.com/design/export.php

Basically you set your character to assume different poses in the timeline (frame 0 he's still, frame 5 he starts the run animation et cetera). Then you create an "frame_list.txt" file where you specify how many frames each animation has and Blender does the rest for you (File\export\MD2)

Hello

I am trying to fix the Bump Map set up for my editor. Am using software renderer, currently the object's texture is set up using the setTexture(Texture t) method. Afterwards I have an option to browse for a normal map file and then this is how I am applying it, following the instructions on the JavaDoc that say to enable environment map first:
obj.setBumpmapped(Object3D.BUMPMAPPING_ENABLED);
obj.setEnvmapped(Object3D.ENVMAP_ENABLED);
obj.setEnvmapDirection(Object3D.ENVMAP_YZ);
obj.setBumpmapTexture(bumpTextName);

But this is the result I get:


The bottom image is the result in JPCT.... it's actually more brownish, i got this screenshot from using a different texture but same bump.... the resolution of both textures is 256x256....

Am I doing something wrong? Thank you very much

Hi Egon

I have only tried this with checkForCollisionEllipsoid, but basically I have the mesh for the four walls of a room and its pavement (all one mesh). If I place the character inside it the check always registers a collision, basically making the character never move. I tried putting the character at different positions inside the room mesh and always no movement. If however I import each of the four walls as distinct objects then the collisions works as expected...

Just checking, is this meant to happen? I am setting each object to CHECK_OTHERS and the character to CHECK_SELF, I have tried with different dimensions for the ellipsoid, from (1, 1, 1) to (10, 10, 10), always same result....


Thank you very much
