TypeError: Tidak dapat membaca sifat yang tidak ditentukan (baca 'kedudukan') menggunakan ThreeJs
Saya cuba menyepadukan model 3D ke latar belakang bahagian wira tapak web saya. Ia berfungsi, cuma apabila saya menukar saiz tetingkap secara manual, model 3D tidak menyesuaikan diri dengan saiz baru. Satu lagi isu yang mungkin berkaitan dengan yang pertama ialah saya mendapat mesej ralat ini dalam konsol, yang merujuk kepada baris 69 kod dalam fail "two.js": Dalam konsol saya mendapat mesej ralat ini:
Keutamaan pertama saya ialah menyelesaikan masalah model 3D yang tidak menyesuaikan diri dengan saiz skrin. Bagi mesej ralat, ia tidak begitu penting jika ia masih berfungsi. Tetapi idealnya, dua orang boleh menyelesaikan kedua-dua masalah.
Adakah anda mempunyai sebarang idea?
