纹理不适用于加工中的形状

Question

我正在尝试将图像应用于我创建的形状。每次单击砍伐按钮时，它都会创建一个图形，我会尝试将我在文件夹中的图片应用为纹理，这样形状就会充满树木，而不仅仅是黑色。我将为海平面和 c02 添加纹理，因此它会随着每个图形而变化我只想先找出森林，所以在森林按钮中我将 img 变量设为森林图片。

当我在控制台中运行时收到错误代码，提示 texture() 不适用于此渲染器。

Answer 1

您使用的方法 (

texture()

) 抛出此错误，因为此功能仅适用于处理中的 P3D 和 OPENGL 渲染器。要解决此问题，您应该在设置时将 P3D 添加到您的尺寸中。这是应该看的：

void setup() {
  size(700, 600, P3D); 
  loadLabelsAndButtons();
}
