== Step_x, step_y and the broken movement syndrome ==

So you compiled the map and suddenly whenever you move you no longer get the animation of moving but just 'appear' on the next tile?

So a while back step_x and step_y were introduced to allow pixel based movement. SS13 does not utilize this. Step_x and step_y are variables that each atom has. The way they work is that as soon as you set any object on the map to use one of these variables, the game interprets that you overrode all default movement code and wrote your own - but you didn't (The code that makes the animation from tile to tile). 

To fix this problem you need to close dream maker (save the project first, obviously). Open your map (.dmm) file in a text editor, such as notepad or notepad++. Search (ctrl+f) through the file for step_x and step_y and remove any reference to it. Once no more step_x or step_y -es are found in the file, save it and open it in dream maker once again. Compile the code and movement should work fine once more. Go to [[Community|the development IRC]] if you need more help.
