Advanced Paths Functions in GameMaker Studio

[@AiguretDuren]

As I've been getting further and further into GMS2, I find myself learning with you. Thank you for the videos! (Also, hello from 2020 💀)

[@glitchydust4015]

mp_potential_step function reminds me of Starcraft 1 AI. I love it hahaha!

[@Tomekeeper]

That was very well explained and demonstrated cleanly. I appreciate it! This helps a lot.

[@robinorbitamusic7456]

Thank you so much. I can see that you're creating memory leaks here in "myPath" variable. But I really love this video. You helped me a lot. Thank you.

[@stardreamix786]

Thank u so much! :)

How the eff do you not have more subscribers? These videos are great!

[@LetsLearnThisTogether]

Ah shucks, thanks.

[@dman4435]

This helps me a lot..... thanks

[@billiephan]

This is amazing, please keep these juice up

[@arunnethrasigamani]

Thanks this is still helpful in 2020

[@facundogaray1020]

amazing tutorial

[@larryteslaspacexboringlawr739]

thank you for gamemaker video

[@trevalgisalgi5290]

this is great

[@3UpGolf]

Great video(s) - been really enjoying them as I learn GMS. Am I correct in assuming the next video you'll be using tilemaps with the mp_grid calls?

[@LetsLearnThisTogether]

+Rob Zimmerman That's the plan. Perhaps not the exact next video I put out, but it will be coming soon.

[@nope1083]

I had my volume up high, your intro made me jump.

[@LetsLearnThisTogether]

Lol.

Hello there. Could it potentially be possible that when the object tries to move towards a corner of the wall object that it gets stuck in the corner? I've been testing out 'mp_potential_path' and 'mp_potential_path_object', and every time without fail the object gets stuck inside the wall object. I even tried to alter the wall's collision from Automatic, Manual, and Full Image. None of them work.

[@adityabhadkamkar8041]

can you make a video for platformer enemy IA, like detecting and following player, with maybe paths too, love your videos . thanks !!!!

[@gelatinousgames3810]

hey so ive got this set so that when the player obj get withing a range of the enemy the enemy will begin to chase it, and if the player leave the range the enemy stops. my issue is that the enemy doesnt stop, but instead tries to get to the last made path end so to speak and ends up going in small circle or bouncing randomly around the area where the player was. any way to fix this? perhaps a way to destroy the created path?

[@gelatinousgames3810]

never mind, im using a states system. and ive made it so after the player is outside of chase range of the enemy, the enemy changes to a "search for player" state where i end its current path and input new movement. so it no long tries to follow the last made path.

[@aaronh560]

Is it possible to attach a path to follow the mouse_x and mouse_y or an object then have an travel around that path?. My experiments have fail and I'm struggling to come across anything similar. Previous I just made my own path in an array by using a path would give me more built in functionality

[@LetsLearnThisTogether]

You sure can. You can dynamically add path points, which is what you'll want to do. Just assign them to the mouse coordinates, probably like once a second.

[@aaronh560]

@@LetsLearnThisTogether Gottcha!. So add the points of the path manually likely during the creation event rather than using a pre-made path. I actually found a cheeky work around where I attached one object to to the path then had another object follow that object and offset the 2nd objects location by the mouse movement and was still able to use the premade path I'd created as I found having the visual guide of the path useful. Thanks for your reply!

that intro

[@maltesvensen1635]

i copied the exact code in the video so that the enemys would walk around walls but they just walk through the walls really slowly. do you think you could help me? code: if instance_exists(obj_player) { mp_potential_step(obj_player.x,obj_player.y,spd,false) } spd stands for the speed that the enemys walk.

[@LetsLearnThisTogether]

Do you have things also set up so they’re solid and the enemies will go around?

[@maltesvensen1635]

oh it's fine i googled the problem a bit and got my answer, working flawless now!

[@CleanCrown]

how can i make my object rotate if its on a path

[@LetsLearnThisTogether]

You need to build in a way to recognize which direction it's facing and then animate accordingly. So you can check things like xprevious and yprevious in the begin step. Then animate/rotate accordingly.

[@CleanCrown]

Beyond Us Games how do i do that

[@fourthkim3715]

It's possible to use this tutorial on Game Maker 1.4 ?

[@LetsLearnThisTogether]

Indeed. I mention where it's different in GMS 1.4 and show how to compensate for it.

[@Taencred]

I just can't get my object to stop animating when it has reached the end of the path. It's not responding to speed, but it's responding to direction. I feel so stupid at the moment..

[@LetsLearnThisTogether]

In about an hour my community day is coming up, and you can hop on my Discord and we can screen share if you want help. Find me on Twitter for the link at 2.

[@Taencred]

Thanks a lot but won't be needed now, I just at this exact moment found the way to fix it. Been scratching my head at that one for an hour or so lol Thanks for the video anyway!

[@dennism4781]

please export to gms 1.4

[@sabriath]

Ug, it's disheartening when I see tutorials with obvious memory leaks.

[@LetsLearnThisTogether]

I can definitely make mistakes. Did I forget to destroy a DS object?

[@sabriath]

@@LetsLearnThisTogether ... when you create a new "goal" position, you destroy the last position, create the new position (which is fine), but then you create a new path and assign it without managing its memory. So every time you create a new goal, it creates a new path. Instead, you should be storing the path ID in the object itself and have it delete the path when destroyed to clean it up. It's not a huge deal, been scrolling through some old tutorials to try and get some programming inspiration in this quarantine crap.
