Hi I uploaded a video of a game I am working on. I'm not good at graphics, so it doesn't look that good yet. It's just a very basic idea of a puzzle style factory sim game. I am looking for something original. The purpose of this thread is to get feedback and ideas on where to go with this project. As of now the concept looks ok, but it is still to easy and probably not interesting enough. You can watch the video here (probably need full-screen to see what's going on): The basic idea is that the green machine spits out blue squares that need to be edited so the shape fits the requested shape as shown on the yellow device. At this point erasers are used to cut away bits from the square. The yellow machine checks if the final shape matches the requested shape. How I made this is by having each part object carry a 7x7 ds_grid. Each cell starts at value 1. When the eraser touches the part the correct cells are set to zero. The part object draws blue sprites (cells) on all positions that have a value of 1. The control part on the yellow machine has a pre-made ds grid. I compare the grids by translating the grid values into variabels and then checking if they match the part variables (a lot of code). If someone knows an easy way to compare 2 ds grids that would be awesome. Thanks for watching. Any additional ideas are very welcome! Do you think this has potential? I'm thinking of making additional devices, also one that can merge several small parts together into larger shapes.
