From e34eb5c26caf4a0a68f8c84f0e02893e4be2eeb6 Mon Sep 17 00:00:00 2001 From: Daniel Rakos Date: Wed, 8 May 2019 17:20:42 +0200 Subject: [PATCH] Fix texture resource reload bug If a non-imported texture resource file (e.g. DDS) gets updated the editor doesn't reload it. The cause of the problem is two-fold: First, the code of ImageTexture assumes that textures are always imported from an image, but that's not the case for e.g. DDS. This change thus adds code to issue a resource reload in case an image reload is not possible (which is the case for non-imported texture resources). Second, the code is filled with bogus calls to Image::get_image_data_size() to determine the mipmap offset when that should be done using Image::get_image_mipmap_offset(). Previous code literally passed the integer mip level value to Image::get_image_data_size() where that actually expects a boolean. Thus this part of the change might actually solve some other issues as well. To be pedantic, the texture_get_data() funciton of the rasterizer drivers is still quite a mess, as it only ever returns the whole mipchain when GLES_OVER_GL is set (practically only on desktop builds) but this change does not attempt to resolve that. --- drivers/gles2/rasterizer_storage_gles2.cpp | 5 +---- drivers/gles3/rasterizer_storage_gles3.cpp | 5 +---- scene/resources/texture.cpp | 17 ++++++++--------- 3 files changed, 10 insertions(+), 17 deletions(-) diff --git a/drivers/gles2/rasterizer_storage_gles2.cpp b/drivers/gles2/rasterizer_storage_gles2.cpp index 13fdd1db734c..3f785889401f 100644 --- a/drivers/gles2/rasterizer_storage_gles2.cpp +++ b/drivers/gles2/rasterizer_storage_gles2.cpp @@ -774,10 +774,7 @@ Ref RasterizerStorageGLES2::texture_get_data(RID p_texture, int p_layer) for (int i = 0; i < texture->mipmaps; i++) { - int ofs = 0; - if (i > 0) { - ofs = Image::get_image_data_size(texture->alloc_width, texture->alloc_height, real_format, i - 1); - } + int ofs = Image::get_image_mipmap_offset(texture->alloc_width, texture->alloc_height, real_format, i); if (texture->compressed) { glPixelStorei(GL_PACK_ALIGNMENT, 4); diff --git a/drivers/gles3/rasterizer_storage_gles3.cpp b/drivers/gles3/rasterizer_storage_gles3.cpp index 95d4bec6113b..661be28e6b12 100644 --- a/drivers/gles3/rasterizer_storage_gles3.cpp +++ b/drivers/gles3/rasterizer_storage_gles3.cpp @@ -1210,10 +1210,7 @@ Ref RasterizerStorageGLES3::texture_get_data(RID p_texture, int p_layer) for (int i = 0; i < texture->mipmaps; i++) { - int ofs = 0; - if (i > 0) { - ofs = Image::get_image_data_size(texture->alloc_width, texture->alloc_height, real_format, i - 1); - } + int ofs = Image::get_image_mipmap_offset(texture->alloc_width, texture->alloc_height, real_format, i); if (texture->compressed) { diff --git a/scene/resources/texture.cpp b/scene/resources/texture.cpp index a5eb950c3660..92172912c2b0 100644 --- a/scene/resources/texture.cpp +++ b/scene/resources/texture.cpp @@ -111,10 +111,12 @@ void ImageTexture::reload_from_file() { Ref img; img.instance(); - Error err = ImageLoader::load_image(path, img); - ERR_FAIL_COND(err != OK); - - create_from_image(img, flags); + if (ImageLoader::load_image(path, img) == OK) { + create_from_image(img, flags); + } else { + Resource::reload_from_file(); + _change_notify(); + } } bool ImageTexture::_set(const StringName &p_name, const Variant &p_value) { @@ -638,7 +640,7 @@ Error StreamTexture::_load_data(const String &p_path, int &tw, int &th, int &tw_ bool mipmaps = df & FORMAT_BIT_HAS_MIPMAPS; if (!mipmaps) { - int size = Image::get_image_data_size(tw, th, format, 0); + int size = Image::get_image_data_size(tw, th, format, false); PoolVector img_data; img_data.resize(size); @@ -660,7 +662,6 @@ Error StreamTexture::_load_data(const String &p_path, int &tw, int &th, int &tw_ int mipmaps2 = Image::get_image_required_mipmaps(tw, th, format); int total_size = Image::get_image_data_size(tw, th, format, true); int idx = 0; - int ofs = 0; while (mipmaps2 > 1 && p_size_limit > 0 && (sw > p_size_limit || sh > p_size_limit)) { @@ -670,9 +671,7 @@ Error StreamTexture::_load_data(const String &p_path, int &tw, int &th, int &tw_ idx++; } - if (idx > 0) { - ofs = Image::get_image_data_size(tw, th, format, idx - 1); - } + int ofs = Image::get_image_mipmap_offset(tw, th, format, idx); if (total_size - ofs <= 0) { memdelete(f);
