I am new to Defold and have very little experience with programming. I’m trying to make isometric shooter.
What would be the best solution to change player sprite (8-dir) based on mouse position relative to player?
I would recommend using 3D models and rotating them. It will save a lot of animation work in the long run. I was using sprites in my game initially but then the camera perspective becomes fixed (if you change things even a bit the 3D effect breaks) and you have to draw the sprites (or render them to sprites from a 3D model) in different angles. You can also apply post processing effects to emulate the 2D sprite effect if you want that way.
The first thing that comes to mind is:
- Get cursor position in world space.
- Subtract character pos from cursor pos to get relative vector.
- Use math.atan2 to get the vector’s angle.
- Round/snap that angle to be one of the 8 directions.
- Use a table with angle keys and image/animation-name values to select the right image for your sprite.
There’s probably some fiddly-ness with step 4. You can google something like, “snap to 8 directions” to find more detailed info about it.
