Glenn,

I am trying to export from Maya 2011 an object that contains animation to POD file but I have a hard problem making it animate in Cocos3D. Could you share your settings on the PVRGeoPOD converter? Which PVRGeoPOD version do you use?

Thanks and I appreciate it,
Alex

thank you, it's work well,except double tap.

Ok sure, in home after 6 o'clock !

@GTC: One thing to remark here:

CGPoint centerPointInParentNodeSpace = [self convertPoint:centerPoint fromNode:theParallaxNode];

Can you share this

[self convertPoint:centerPoint fromNode:theParallaxNode];

method also?

Hey, good job :). I wonder how this works with the UIKit friendlier Cocos2D 2.0 :).

So, this is my fixed handlePitchZoom.

- (void)handlePitchZoom:(NSSet *)touches withEvent:(UIEvent *)event {

    UITouch* touch1 = [[[event allTouches] allObjects] objectAtIndex:0];
    UITouch* touch2 = [[[event allTouches] allObjects] objectAtIndex:1];

    // calculate scale value
    double prevDistance = ccpDistance([touch1 previousLocationInView:[touch1 view]], [touch2 previousLocationInView:[touch2 view]]);
    double newDistance  = ccpDistance([touch1 locationInView:[touch1 view]], [touch2 locationInView:[touch2 view]]); 

    CGFloat relation = newDistance / prevDistance;
    CGFloat newScale = self.scale * relation;

    if ((newScale >= minScale) && (newScale <= maxScale)) {

        CGPoint touch1Location = [GST.layerNode convertTouchToNodeSpace:touch1];
        CGPoint touch2Location = [GST.layerNode convertTouchToNodeSpace:touch2];

        // calculate center point between two touches
        CGPoint centerPoint = ccpMidpoint(touch1Location, touch2Location);

		// store center point location (ScrollableView space)
        CGPoint centerPointInParentNodeSpace = [self convertPoint:centerPoint fromNode:GST.layerNode];
		CGPoint oldPoint = ccp(centerPointInParentNodeSpace.x * (self.scale), centerPointInParentNodeSpace.y * (self.scale));
		self.scale = newScale;

		CGPoint newPoint = ccp(centerPointInParentNodeSpace.x * (self.scale), centerPointInParentNodeSpace.y * (self.scale));
		CGPoint diff = ccp(oldPoint.x - newPoint.x , oldPoint.y - newPoint.y);

        [GST.layerNode setPosition:ccp(GST.layerNode.position.x + (diff.x*(1/self.scale)), GST.layerNode.position.y + (diff.y*(1/self.scale)))];
    }
}

The problem was that the original code just scale the outermost layer but I needed to scale my working layer also which is the part of CCParallaxNode.

So this is the key

[GST.layerNode setPosition:ccp(GST.layerNode.position.x + (diff.x*(1/self.scale)), GST.layerNode.position.y + (diff.y*(1/self.scale)))];

I also adopted some position changing and scaling for my working node (GST.layerNode).

Bill,

In Maya it is Y-up, but i don't think that's it. I already tried creating new Maya project with Z-up per your instructions and it didn't fix this. In fact, it seemed to work the same. Also, all my non-camera animations work fine either way. I also experimented with changing the rotation order but didn't see any effect.

In either case, the animation is the problem. The animation is pointing the camera the wrong way. I did the X-rotation to counter that, as you suggested.

Just wanted to let everyone know about this and how to correct it.

Thanks for responding.

Regards,
Glenn

In Maya, what is the orientation of the axes?

Like OpenGL, cocos3d assumes that the Y-axis represents "up" and that the default orientation of the camera is to point down the negative Z-axis. That puts the positive X-axis on the right.

However, the Collada2POD converter swaps the Y & Z axes during conversion. So, in your 3D editor, you should orient the Z-axis as "up". See the notes on Coordinate Systems in the cocos3d Collada2POD Instructions for more on this.

By applying a 90 degree rotation of the camera on the X-axis, it looks like you are effectively re-doing that axis-swap (or countering it).

Could it be that your world in Maya has the Y-axis as up, instead of the Z-axis? Or that perhaps the PVRGeoPOD tool is not swapping the Y & Z axes as expected?

...Bill

I'll post it as soon as possible because I'm not with my computer ;)

Thanks!

I have successfully created a scene in Maya, exported it with PVRGeoPOD and imported it into a cocos3d project. The scene contains mesh and camera animations which I want to use in my project. I found that the mesh animations worked perfectly, but camera animations were not oriented properly.

I have made no changes to the default axis in Maya, and mesh animations are working well, so it would be great if camera animations did as well. I have some complex camera moves that would be hard to recreate in Xcode. Though the workarounds I came up with do work, it would be better if cocos3d could import camera animations without need to make any changes.

To work around this issue, first I copied the camera animation to a mesh cube in Maya, then in Xcode I copied the mesh animation to the camera. It worked perfectly!

Next, I wanted to see what was being changed, so I experimented with creating a structural node, making the camera a child, then moving the animation to the structural node. This way I could rotate the camera independently of the animation. Here's what I came up with:

// Get the camera from the POD file
    camera1 = (CC3Camera*)[self getNodeNamed:@"camera1"];
    self.activeCamera = camera1;  

    // Put this camera under a parent node
    camParent = [[CC3Camera alloc] initWithName:@"camParent"];
    [self addChild:camParent];
    [camParent addChild:camera1];

    // *** HERE IS THE CAMERA ANGLE CORRECTION ***
    [camera1 rotateByAngle:-90 aroundAxis:CC3VectorMake(1, 0, 0)]; // The camera direction appears to be rotated from pointing to -z to y, rotate it back
    camParent.animation = camera1.animation; // Copy the animation to the parent node
    camera1.animation = NULL;

    // Run the animation from the POD file
    [camParent runAction: [CCRepeatForever actionWithAction:[CC3Animate actionWithDuration:10.0]]];

So my question is this: Does PVRGeoPOD do this, and if so can it be corrected in the cocos3d import module?

@xmawiel - If the boundingRect height matches the windowRect height, there should be no movement. Also you could limit the y-value of the point you give to centerOnPoint. Other than that you'd have to hack it.

How do I limit this class to only pan in the x axis?
Also, Is there a way to only "CenterOnPoint" only in the x axis?

Solved it

CC3Camera* cameraFromBehind;
cameraFromBehind = (CC3Camera*)[self getNodeNamed: @"TrackingCamera"];
cameraFromBehind.target = activeTruck.turnTable;
cameraFromBehind.location = cc3v(-10,0,5);
cameraFromBehind.shouldTrackTarget = YES;
self.activeCamera = cameraFromBehind;

I added

cameraFromBehind.location = cc3v(-10,0,5);
cameraFromBehind.shouldTrackTarget = YES;

which repositioned the camera to a nicer position and then seems to tell the tracking node to keep tracking without it, just doenst update

Hi,

I've just started trying to create alternate camera views.

I created a camera in blender that is a child of a node.

I then set it up in cocos3d as follows

CC3Camera* cameraFromBehind;
cameraFromBehind = (CC3Camera*)[self getNodeNamed: @"TrackingCamera"];
cameraFromBehind.target = activeTruck.turnTable;
self.activeCamera = cameraFromBehind;

When the world loads for a split second it has the correct orientation then it rotates 90 degrees to the right.
I have commented out all my world update code, but it seems to happen every time, am I missing something obvious?

Thanks
Duncan

@GTC: How did you solved? I'm also trying to solving this problem... your answer would help me :)

Thanks!

if we put self.controller = [CCPanZoomController controllerWithNode:self] ; while declaration then a black background appears below entire map and it wont show layer color then

should it be set to your scene or should it take tilemap as node ?? coz in that case it should layer background color

anyone tried changing the background color of tilemap ???

I mean to say the color outside the boundries od tilemap

in this case it has blackcolor

How can we change it

FYI, In my game I'm using this and works correctly :)

http://www.cocos2d-iphone.org/forum/topic/2229

stuck for a while now :( ..please help

by tile coordinates i mean .. tile index in tile map like {0,1} or {0,2} etc

by tile center point i mean tile.position which i get by CCSprite *tile = [self.portsLayer tileAt:ccp(Index.x,Index.y)];

i want to center my map to this tile .. which i am unable to do by "centerOnPoint:"

answer by mobilebros:
@muzzammil - Ok it's tile.position you want to use then, which node/layer is the controller controlling? It should be portsLayer I would imagine or one of its ancestor's that shares the same coordinate system.

@mobilebros: contoller is controlling the layer which has a tilemap on it .. and portsLayer is a layer on the tilemap.I have integrated many other feature like move on tile location etc and all are working well except for center location..

cannot figure out this problem :(

that was easy!

... and I was stupid for not having thought it by myself :)

Thanks again!

@ffede81 - You should only have to do:

CGPoint pos = [node convertTouchToNodeSpace:touch];

where node is most likely "self" it's the layer/node you're are adding the sprite to.

I think the first one :D When I pan or zoom and then I touch on the screen to create a sprite, it actually appears in a different position compared to my touch. I used to create a CGPoint "offset" that registered the new position of the layer (this works just for the pan, not sure about the zoom) and I did a ccpSub or ccpAdd to the touch location to get the new position and create the sprite in the right position. I don't know though if this is the right way to do it, probably there's a simpler method already implemented in cocos2d :)

Thanks @AppTinker, I'll add the fix to the repo soon.

@ffede81 - Are you trying to get the coordinates of the last pan/zoom touch, specifically in the node's coordinates? Or are you capturing your own touches and need to know how to convert that to the right coordinates?

thanks guys! The new disabled method has solved the issue properly!

Now I just need to get the right touch coordinates for my touches after panning/zooming when I create sprites. I managed to do something by creating an offset that I add to every touch event but I feel like this is not the good way to do it. How would you guys do it? :)

Thanks a lot for your help!

I think @Krithik B might be right, if so then try replacing disable with this one:

-(void) disable
{
    [[CCTouchDispatcher sharedDispatcher] removeDelegate:self];

    for (UITouch *touch in _touches)
        [self ccTouchCancelled:touch withEvent:nil];
}

I guess I would have thought cocos would handle this for you (being in a touch cycle when removeDelegate is called but still forcing the complete cycle), but it appears the touch events are just lost.

@ffede81

I think i got your problem. Whats happening is the touch reference in touches array will be still there, so you need to remove it.
So whenever you disable or enable the controller remove all the touch objects from the touches array :)

@goodeats2009 - Sorry, I guess I don't really know; perhaps a video if you can might show it better.

@ffede81 - It doesn't sound like you're doing anything wrong; somehow the controller must think there are two touches down. It does try and keep a reference to them... I'll have to create a test like what you're doing and see if I can figure it out.

Solved! :)
