Hello, I am new to Minecraft modding and started working on a cement mod for 1.7.2. Goal: A placeable liquid that dries into stone (maybe with an intermediate block) within seconds. I followed the tutorial at http://www.minecraftforge.net/wiki/Create_a_Fluid resulting in: - new liquid cement - cement bucket can place and pickup source block Now, I cannot figure out how to let it dry. If I use an ExecuterService with a scheduled delay, bugs occur since world changes are not taken into account if I call world.setBlock(x, y, z, Blocks.stone); I noticed that there is always just one instance of the fluid block, and the displaced blocks are the same with increased metadata. I wanted to use onBlockAdded(final World world, final int x, final int y, final int z) to call a world.scheduleBlockUpdate(x, y, z, this, tickRate); but the scheduledBlockUpdate does not call updateTick (only by onNeighborBlockChange or something). In addition, how should I replace the flowing fluid by stone if they are one and the same object? If I replace the original source block; the adjacent blocks disappear. I tried a tick update loop with timestamp comparison but since they are the same block, they get turned to stone simultaneously. public final static int DELAY_DRY_MS = 3000; // 3sec ... @Override public void onBlockAdded(final World world, final int x, final int y, final int z) { super.onBlockAdded(world, x, y, z); dryingStartTime = System.currentTimeMillis(); } @Override public void updateTick(World world, int x, int y, int z, Random rand) { if (System.currentTimeMillis() - dryingStartTime >= DELAY_DRY_MS) { world.setBlock(x, y, z, Blocks.stone); return; } else { super.updateTick(world, x, y, z, rand); world.scheduleBlockUpdate(x, y, z, this, tickRate); } }
