CCColorLayer inside Parallax view seems to always cover Box2d DebugDraw.

Greetings,

I searched and found no mention of this, apologies if it has been discussed before. I am using Cocos2d 0.99-release and Box2d

Anyway, I added a CCColorLayer to my parallax layer (giving it the lowest Z order) and when I do, it hides (covers) the DebugDraw data of Box2d. I experimented with other Z value but DebugDraw data is still being covered by the ColorLayer. Oddly it only seems to hide the DebugDraw data, other parallax layers are showing up correctly.

I tried adding the color layer directly into the game layer (as lowest Z order) (same layer I add the parallax view to), and it works, but I am curious as to how I could get this working properly inside the parallax node.

Any help would be appreciated.
Regards,
Q

You may need to go change the GLESDebugDraw functions to specify a z value for all of its vertices. Just pick something big and it should always be on top of your other graphics.

for example in DrawAABB

void GLESDebugDraw::DrawAABB(b2AABB* aabb, const b2Color& c)
{
	glColor4f(c.r, c.g, c.b,1);

	GLfloat				glVertices[] = {
		aabb->lowerBound.x * mRatio, aabb->lowerBound.y * mRatio, 1000.0f /* Adding Z */
		aabb->upperBound.x * mRatio, aabb->lowerBound.y * mRatio, 1000.0f /* Adding Z */

		aabb->upperBound.x * mRatio, aabb->upperBound.y * mRatio, 1000.0f /* Adding Z */

		aabb->lowerBound.x * mRatio, aabb->upperBound.y * mRatio, 1000.0f /* Adding Z */

	};
	glVertexPointer(/* Change from 2 to */ 3, GL_FLOAT, 0, glVertices);
	glDrawArrays(GL_LINE_LOOP, 0, 8);

}
