Using Paths alongside a Solid object to move a platform around in a specific way?

[ManeaterMildred]

Hello! Title should be pretty explicit- I'm wondering about using Paths along with a Solid to make them move in a very specific way.

Unfortunately, the player does not follow along the platform in this way, and while I tried looking at the already-existing platforms for example, trying to use a Path on those leads to a similar problem, except now the graphics are also escaping-

This is the added line of code for starting the path I made in obj_platform_basic.

So yeah, just wonderin' if there's a way to make this work! Sorry if the answer is obvious, I've been a bit stumped on this.

I've never used Paths but I think it has something to do with the code execution order and how the Path system works. You need to make sure objects moves along the path first, then obj_act_solid() is executed. I'd be grateful if you attach your project file so I can take a look whenever I have time to deal with this kind of stuff

Sure thing, here: https://drive.google.com/file/d/1UGTnJxAbh5vYwAr778iV5g03Jc-b6W2L/view?usp=sharing
(I have it on restricted so other peeps don't randomly try to download it, you'll have to ask for access- Would've send a DM but alas, Github doesn't allow for DMs lmao.)

The obj_collision_move I duplicated to use the path is in Objects>Common, as usual.

I sent the request

Accepted! Thanks for giving it a look, haha.

Okay, so, according to the GameMaker docs:

When following a path, an instance's position is updated after the Step event, so during the Step event its x and y position will be the same as its xprevious and yprevious (unless manually modified in the Begin Step or Step events).

This means, we should do a workaround. Simply using End Step event won't work correctly due to how GameMaker executes events between objects, TLDR; we need to make sure it is somehow run after the Step Event but before c_framework's End Step Event

To do this, open c_framework, End Step, and add the code below right before the with obj_player loop (so it will be basically the very first thing End Step will do there):

with c_object
{
	event_perform(ev_other, ev_user10);
}

Now for your object, use User Event 10 instead of Step Event. It should work just fine

[ManeaterMildred]

Hm, doesn't seem to work.

Even with path_start called in User Event 10 and with the condition fulfilled, the block won't move.

Honestly, if paths just turn out to be incompatible with the framework, that's totally fine, I'll just have to find a different method of doing path movement like that, but it is odd It's not working.

[TrianglyRU]

I'd not reply with my solution if I didn't test it first. Your implementation is simply incorrect.

c_framework's End Step should look like this:

For your object, you should move EVERYTHING from Step Event into User Event 10. Step Event should not be used in this case

[ManeaterMildred]

Oh I misread, apologies, that's totally on me. Yeah, I just tested it out after fixing the end_step and now it works just fine!

Thank you so much and sorry for that mishap, I somehow didn't realize I messed put the end_step setup and thought I just had to add the event_perform 10 on obj_player too, which... When I think about it for two seconds, doesn't make sense- Hah.

Thanks, again! Works just fine now-

Glad to help!
