Picked Upload! This is a picked upload! It showcases some of the best talent and creativity available on MTS and in the community.
Free your sims from carrying their toddlers up and down stairs! They have better things to do!

This is a combination script, tuning, and default replacement mod that lets toddlers use stairs.

The default replacement part replaces the StairHelper object's OBJK with a version pointing to a custom Stairs class that toddlers can interact with. If this mod is inserted into an ongoing game, existing stairs may need to be deleted and re-purchased for the replacement to take effect.

The tuning part edits the LocomotionConfig XML to insert stairs animations for toddlers, demonstrated in the gifs above. Toddlers who have learned to walk will use the slightly faster standing animations, while those who haven't will crawl.

The script part (in addition to letting toddlers use stairs at all) replaces the Go Here interaction and toddlers’ interactions with some of the objects they can use, lifting the restriction that blocks those interactions from being used by a toddler not on the same level of the lot as the object in question. (See Conflicts for the list of un-restricted interactions)

Expected Updates
  • Animations will be upgraded once my skills improve enough - this has been my first attempt at animating, so think of the current animations as a beta version.
  • Currently, only straight staircases have been unlocked for toddlers' use; spiral staircases to come, they have separate code.
  • Stairs will be unlocked for kittens and puppies once I learn to animate pet rigs.

This mod will conflict with any others that edit the LocomotionConfig XML or replace the OBJK of the StairHelper object. It also seems to conflict with the NRaas NoCD mod, unclear why.

It may also overwrite the effects of mods to the Play interactions on the xylophone and pegbox, the Play With interactions on toy box toys and stuffed animals, the Play With Blocks interaction on the activity table, the Use interaction on the potty chair, and (toddlers’ version of) the Read interaction on toddler books.

There are two versions available to download, one compatible with NRaas GoHere (v44) and one not; only install one. Don’t install the GoHere-compatible version if you don’t have GoHere - it will not work and none of your sims will be able to move, it'll be bad. If you use the non-GoHere-compatible version with GoHere, nothing bad will happen, but it'll undo some of the improvements GoHere applies to the Go Here interaction.

And finally, this mod was made on patch 1.69! It's unclear if it works well with 1.67 or not, still figuring that out.

A huge thank you! I can't believe we had to wait so long to be able to do this in The Sims 3. No more need to teleporting them when the parents are busy! I tried for a few minutes of play with 5 toddlers and it works pretty well. It sometimes happens that when going up the stairs, the animation "stumbles" and it falls back down so I have to start over, but that's rare. Also, the only thing I can order them on a different floor is to go potty. I can't do anything with toys or other sims for example. It's annoying but it's only a detail compared to the practicality of your mod!
(Sorry for my english lol)

i tried using the gohere version several times, it doesnt seem to be working. I do not use the NoCD one so there should be no conflict
