Okay, writing this here to get down some thoughts for later (after a shower), and also in case it might help someone else down the line.<\/p>\n

A ladder is a bit more complex a scenario than I originally anticipated. It’s not enough to just say so and so object is ‘nearLadder’ and allow them to float around on the Y axis. There are a few different scenarios that happen when a player gets near a ladder, which all need their own behaviors.<\/p>\n

1: Player walks next to bottom of ladder<\/h2>\n

\"ladder_walk_over\"<\/p>\n

In this most basic scenario, the player could have some kind of variable set that it is over a ladder and can climb. Being able to climb should allow the player to modify their Y location via input. The basic climbing stuff.<\/p>\n

2. Player\u00a0climbs ladder<\/h2>\n

\"player_climb_ladder\"<\/p>\n

For this scenario, some basic climbing animation could play. In my case, I am setting the gravity scale for the player to 0, but that has it’s own issues.<\/p>\n

3. Player\u00a0walks next to top of ladder<\/h2>\n

\"player_top_ladder_float\"<\/p>\n

And here is the issue. If you set the gravity scale to 0 when near a ladder, coming from the top makes the character float! Instead, I think a variable isClimbing could get set if the player presses up or down while over a ladder, otherwise, the player falls as normal.<\/p>\n

4. Player\u00a0climbs partially up ladder then jumps<\/h2>\n

This should set isClimbing to false, and since I’m using grounded checks to allow climbing, ladders should ground the player the whole way.<\/p>\n

 <\/p>\n

So a state machine would be something like:<\/p>\n

\"Screen<\/a><\/p>\n

 <\/p>\n

Well that’s a start anyway.<\/p>\n
