问题描述
我正在使用SKShapeNode创建一个像山一样的对象。我使用CGMutablePathRef给我的路径分数
I am using SKShapeNode to to create a mountain like object . I use CGMutablePathRef to give the points to my path
SKShapeNode *shapenode = [[SKShapeNode alloc] init];
CGMutablePathRef path = CGPathCreateMutable();
CGPathMoveToPoint(path, NULL, 0, 0);
......
for (int i = 0; i < [refData count];i++) {
CGPathAddLineToPoint(path, NULL, ((float)i/[refData count])*screenWidthBoundry, [[refData objectAtIndex:i] doubleValue]);
}
CGPathAddLineToPoint(path, NULL, screenWidthBoundry, 0);
CGPathAddLineToPoint(path, NULL, 0, 0);
shapenode.path = path;
shapenode.antialiased = YES;
shapenode.fillColor = [SKColor colorWithRed:17.0/255.0 green:108.0/255.0 blue:125.0/255.0 alpha:1.0];
//shapenode.strokeColor = [UIColor clearColor];
shapenode.lineWidth = 1.0f;
shapenode.physicsBody = [SKPhysicsBody bodyWithEdgeChainFromPath:path];
shapenode.physicsBody.affectedByGravity = NO;
shapenode.physicsBody.categoryBitMask = CollisionTypeMountain;
shapenode.physicsBody.collisionBitMask = 0;
shapenode.physicsBody.contactTestBitMask = CollisionTypeBird;
CGPathRelease(path);
return shapenode;
我的问题是SkShapeNode正在减慢iPhone 4上的动画速度（在iPad和iPhone 5上顺利运行）但仍然不是60 fps）并消耗大量内存。我可以缓存skshapnode对象以顺利运行动画吗？任何帮助表示赞赏!!
My Problem is that SkShapeNode is slowing down the animation on iPhone 4 (runs smoothly on iPad and iPhone 5 but still not 60 fps) and consuming lot of memory. Can I cache skshapnode object to run animation smoothly ? Any Help is appreciated !!
推荐答案
我遇到了同样的问题，SKShapeNodes占用了太多的CPU资源并导致帧率下降。使用SKView的 textureFromNode：方法创建SKTexture。现在创建一个SKSpriteNode，其中包含生成视图的SKTexture。这将解决您的性能问题。
I was running into the same problem with SKShapeNodes consuming too much cpu resources and killing the framerate. Use your SKView's textureFromNode: method to create an SKTexture. Now create an SKSpriteNode with the SKTexture your view generated. This will fix your performance issues.
