GL_CLAMP_TO_EDGE should be used in NPOT textures

I have two images:

  1. PNG (sRGB) 64x64 (dowloaded from network)
  2. PNG (sRGB), ported from fla to png, then, from png to jpg with sRGB, then to PNG (sRGB).

I'm trying to fill polygon with texture, created from this image:

CCTexture2D *texture = [[CCTextureCache sharedTextureCache] addImage:spriteName];

    polygon = [[[PhisicsFilledPoligon alloc] initWithPoints:points
                         andTexture:texture] autorelease];

PhysicsFilledPolygon is kind of PhysicsSprite for box2d, but with overrided 'draw' method:

-(void) draw 
{
    ccGLBindTexture2D( [self.texture name] );

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);

    ccGLEnableVertexAttribs( kCCVertexAttribFlag_Position | kCCVertexAttribFlag_TexCoords );

    [prog use];
    [prog setUniformForModelViewProjectionMatrix];

    glVertexAttribPointer(kCCVertexAttrib_Position, 2, GL_FLOAT, GL_FALSE, sizeof(CGPoint), areaTrianglePoints);
    glVertexAttribPointer(kCCVertexAttrib_TexCoords, 2, GL_FLOAT, GL_FALSE, sizeof(CGPoint), textureCoordinates);

    glDrawArrays(GL_TRIANGLES, 0, areaTrianglePointCount);
}

when I'm tring to use 1st image for texture, all works fine. But since I'm using 2nd one, app crashes with error:

*** Assertion failure in -[CCTexture2D setTexParameters:], /Users/SentineL/Documents/squirrels ios/squirrels/libs/cocos2d/CCTexture2D.m:743

What ever image I'm trying to use, result is same error. Cocos2d version is 2.0 rc0. Here is starting cocos2d info:

Where is my problem?

Solution

  • You're using texture with Not-Power-Of-Two dimensions.
