X-Git-Tag: xonotic-v0.1.0preview~2747 X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=0144ec3bdff2b7e8397be064cb7850a1ece7bce9;p=xonotic%2Fdarkplaces.git Add TEXF_PERSISTENT and R_PurgeTexture which only frees textures if that flag isn't set. Changed the SkinFrame purging code accordingly (and the default texture creation calls). Fixed a bug that caused dynamic textures not to survive map switches (LoadExternal would try to load pixel data because ->base was set to NULL - it now restores the pointer in SkinFrame_Find..) git-svn-id: svn://svn.icculus.org/twilight/trunk/darkplaces@7737 d7cf8633-e32d-0410-b094-e92efae38249 --- diff --git a/cl_gecko.c b/cl_gecko.c index 9fd21293..5885f8ab 100644 --- a/cl_gecko.c +++ b/cl_gecko.c @@ -68,7 +68,7 @@ static void cl_gecko_updatecallback( rtexture_t *texture, clgecko_t *instance ) static void cl_gecko_linktexture( clgecko_t *instance ) { // TODO: assert that instance->texture == NULL - instance->texture = R_LoadTexture2D( cl_geckotexturepool, instance->name, DEFAULT_GECKO_WIDTH, DEFAULT_GECKO_HEIGHT, NULL, TEXTYPE_BGRA, TEXF_ALPHA, NULL );
