xscale

问题 I use SKNode's xScale property to flip my sprites horizontally. Now, after updating iOS to version 7.1 horizontal flip causes my objects to sink inside the ground. (See animation below). The problem occurs only with xScale property. Vertical flips work fine. // Init { SKSpriteNode* ground = [SKSpriteNode spriteNodeWithColor:[UIColor blackColor] size:CGSizeMake(winSize.width, 150)]; ground.position = CGPointMake(winSize.width/2, ground.size.height/2); ground.physicsBody = [SKPhysicsBody

问题 I am playing around with a PXA270 Xscale development board (similar to the Gumstix), and was provided a cross compiler, but it is GCC 3.3.3. I would like to learn how to build my own cross compiler, so I can customize the setup, but have had trouble getting crosstools and crosstools-ng to successfully build a toolchain. My main needs are using GCC 4.2.X and the ability to use soft float. I am running Ubuntu 9. Does anyone have any recommendations or advice on building a toolchain for such a
