I'm currently trying to learn how to make mods in forge and i have been following "Tutorials by kaupenjoe" on youtube. In the tutorial he makes a block called speedyblock. I removed the speed that the block gives, and instead wanted to make a sort of minigame where the only block that's allowed to stand on is the speedy block. I want to give the player a single speedyblock every 5 seconds. I have the event and logic all set up, i just don't know how to actually give the player the item. I tried using the players "addItem" function with a "new Itemstack(new blockItem(ModBlocks.SPEEDY_BLOCK, new Item.Properties))", however that only gave the player two items with the "missing texture" texture. Does anyone know how to do this?
