SCNText 不显示 [英] SCNText Not Displaying

问题描述

我的 SceneKit 应用程序中有以下代码，但由于某种原因，文本从未显示在屏幕上.

I have the following code in my SceneKit application but for some reason the text never shows up on the screen.

 let text = SCNText(string: item.label, extrusionDepth: 4.0)
            text.firstMaterial?.diffuse.contents = UIColor.white
            text.font = UIFont(name: "Arial", size: 35)

            let textNode = SCNNode(geometry: text)
            textNode.position = SCNVector3(-0.2 + x, -0.9 + delta, -1)

            self.node.addChildNode(textNode)

推荐答案

不要使用 .font，请尝试使用 .scale.即使是字体的 1 仍然是一米高，因此可能需要将其缩小.这对我有用: textNode.scale = SCNVector3(0.01,0.01,0.01)

Instead of using .font, try using .scale. Even a 1 for font is still a meter tall, so scaling it down might be needed. This worked for me: textNode.scale = SCNVector3(0.01,0.01,0.01)
