I would like to add texture to my model but I keep getting this error . Any help would be appreciated. Thanks
for (String i : faces) {
for (String j : i.split(" ")) {
iCoords[faceIndex] = (short) faceIndex++;
String[] faceComponent = j.split("/");
String vertex = vertexes.get(Integer.parseInt(faceComponent[0]) - 1);
// this line throws NFE
String texture = textures.get(Integer.parseInt(faceComponent[1]) - 1);
String vertexComp[] = vertex.split(" ");
String textureComp[] = texture.split(" ");
for (String v : vertexComp) {
vCoords[vertexIndex++] = Float.parseFloat(v);
}
for (String t : textureComp) {
tCoords[textureIndex++] = Float.parseFloat(t);
}
}
}

arrays can't be parsed as integers / floats. Use a debugger and fix your split pattern. – Menaj
String doesn't look like[number]//[number]
(e.g.1//2
). You can't use a double slash (or more) with your current code. – Tomsplit("/+")
instead ofsplit("/")
. – Tom
