description: "Pituicat can now (partly) interact with movable objects"
---

Hi there,

As my apprenticeship slowly winds down and comes to an end, I have found the
time again to work on "Pituicat". This time I tackled the problem of
interacting with movable objects. This was all possible due to the friendly
Haskell GameDev community on Discord, which gave me valuable hints here and
there, when I needed them.

This meant another rework on the collision handling side of the code, so I had
to break the collectible powerups, but I hope to get them back shortly.

Also I changed the way player movement is handled. I used to apply the move
velocity as a physical velocity before doing collision checks, which tended to
backfire and cause random breakage and unforeseen behaviour, especially when
applying velocity updates after collision. Then just shortly I got the valuable
hint, that player movement should not be really applied as a physical force but
rather "hacked in". This I managed to do, which now saves me a lot of headache
when updating the player's velocity.

I rendered a short Video of some interaction between the player and placed
objects on the map. Vertical interactions work well, as you can see, but
horizontal still need work, which is why I chose to ommit them here.

  <source src="/vids/2021-07-25.webm" type="video/webm" />
</video>

I am quite happy to make progress on this project, no matter how small that
progress seems to be.

As always, you can look into the code and game design documents in
[the project's gitea repository][gitea].

I wish you all a pleasant sommer. Don't melt.

Keep calm and wash hands.
