I am please to announce Gridworld v1.13. It contains all fixes of v1.12 which I had to recall, plus a few extra fixes and additions. Unfortunately, saved world and creatures from older versions will no longer work, but exported creatures still work fine. - Memory has been optimized for lower use of memory and smaller file sizes. This should also reduce the chance of crashes or eliminate them for users who have experienced random crashes. - Crashes on saving or loading should be fixed. - Slider values can now be changed manually by typing. Just click on the value and then type the value. - Added a short description for each neuron type in the neuron property windows. - Clicking on neuron count in the microscope window will now open the neuron property window. - Changed the default colors of the UI. Thanks Faker for the suggested colors. - Fixed bug in which carcasses could replace other objects on the grid - Added friction as a variable for the tiles. - Introduced Sonar input neuron. - Meteors can now be dropped automatically - Fixed bug in which some settings in the world editor where not saved for tiles,rocks,carcasses and lights. - Added maximum carcass slider to carcass window in world editor - Fixed bug in which creatures would not die when they overfed. - Carcasses now turn darker when they are being eaten. - Fixed bug in which placing something on the far right side or top of the grid did not work. - The color brightness of carcasses can now be manually changed in the UI - Added window which shows java used heap , maximum heap and used JRE version. - Repostioned autosave text to the center of the screen. - Added new variable "random target tile "to photosynthesis neuron. If checked, target tile is selected randomly within range. - Colors of edge and background are now properly saved. - UI menu has been put into the option menu. - Reduced some maximum values of placement tools to managable values. - Added key command for opening and closing help window. - A pdf manual can now be found in the steam folder. It is not finished yet, but does cover a few topics. EDIT: had to a small hotfix to fix an important issue. - fixed bug in which creatures could eat rocks! - fixed bug in which replacing a creature with a rock would show a detached carcass symbol. - rocks are now unmovable by default.
