GSoC 2017: Sludge Engine Week 4<\/h1>\n

Week task conclusion<\/h1>\n

Generally, this 3rd week of GSoC project was good: the input works and we are able to reallly \u201cplay\u201d the game. Bugs are cleared for the game demo Verb Coins now and there are only z-Buffer stuff left to get it fully work.<\/p>\n

Again, thanks to my mentors _sev(Eugene Sandulenko), t0by(Tobia Tesan) and all scummvm team members that has helped me on input and bug fixes during this week.<\/p>\n

    1. When setting opacity for transparent surface blitting, we need to modify the second parameter of TS_ARGB() instead of the first one, which is strange.\u00a0Related line<\/a><\/li>\n<\/ol>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

      What\u2019s for next week: z-Buffer Image & new game<\/h1>\n

        \n
      1. Get\u00a0Z-Buffer<\/a>\u00a0up: it is used for different areas of a scene which can obscure character graphics, such as foreground silhouettes, doorframes and furniture.<\/li>\n
      2. Add game fallback detection<\/li>\n
      3. Add game\u00a0Robin\u2019s rescue<\/i>\u00a0<\/a>and test<\/li>\n<\/ol>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

        Some findings about sludge<\/h1>\n

        Sludge input<\/h2>\n

        Sludge input is using common sdl input functions<\/p>\n

        Freeze and unfreeze game scene<\/h2>\n

        In sludge, whenever a dialog, reaction menu is popped up, the scene get frozen. The principle is that they make a screenshot of every thing on the background and copy interactive elements to a temporary variable and set them to null. Then, when we unfreeze, we restore them all.<\/p>\n
