I’m learning unreal engine and want to make game I know like tetris ect. to help me understand the program. I have learned how to make platformer 2D games, but I’m stuck where to go from making a grid and having the block snap in the grid and not overlap each other. Any suggestions please.

If you are working in 2d space I would get the X and Y coordinates of the object and pass them through the node “Snap To Grid (Float)” (separate for X and Y).

If you are working in 3d space then there is “Vector Snapped to Grid” that takes in a vector and grid size and outputs the snapped coordinates.

To create a grid for snapping blocks in Unreal Engine:

  1. Use a 2D array to manage grid positions.
  2. Round block positions to the nearest grid point (Round(GridSize)).
  3. Check for overlaps before placing blocks.
  4. Store and update grid data dynamically.

For a practical example of block-snapping mechanics, check out this game. Hope this helps—good luck with your project
