Help with water please!

Archive: 14 posts


Hi, this is my first ever post, I've only recently stumbled upon this site, yes I know I'm about 2 years late to the party!

Anyway, over the last couple of weeks I've finally started creating with purpose in LBP but I need some advice on the global water object. As part of the level I'm constructing I have a large shaft (no sniggers) that the player must ascend via platforms and swings, meanwhile as the player climbs the water level is rising. The problem I have is below the water level I placed a horizontal platform with sack boy eating fish attached but I can't find a way of syncing the timing of the water level and the platform with the monsters on.

Water seems to rise far faster than the piston powered platform. Is this a trial and error type of problem and a matter of tweaking the piston and water level timings until they sync or is there a better way? I'm using the same sensor to trigger the water and piston.

Hope my question makes sense, and I hope someone can help!
Ps a big thank you to the people responsible for the LBPC Logic levels and tutorials, very inspirational and helpful to a noob creator like me!

just use the logic!! put a key on a cube connected to a piston and a switch at the end and set the switch to speed, but i think this should do the trick...
(i can't see your level so if this doesn't work, sorry)

Sorry for being a noob but your solution sounds like you've made a delay switch, not sure how that helps?

Simplest way for me to describe it is think about an elevator going up and syncing water so it rises in time with it. It's frying my brain, there's got to be a very simple answer ... ?!

You will have to mess with either the global water timing or the piston timing until you get in syncronized. 2010-08-24 22:50:00

Thanks, that's all I figured I could do, bit of a pain but nice to know I hadn't missed an easier way! Cheers buddy2010-08-24 22:53:00

Would a physics-based solution work?

What if the fish were suspended from something which floats on the water surface, then the fish would rise at the same speed as the water.

Stability issues?

Don't think it'd work with something floating on the water, ideally I want the the fish to be driven by a piston so they're snapping at the players as they climb the shaft. I think I'm just gonna tweak and tweak the individual timings until I've got it synced perfectly.2010-08-25 16:56:00

I have an idea! (BTW my first post EVAH)
If you put a water switch set to directional on the platform with the fish,
then attached the switch to the piston, whenever the water rises above the platform the platform goes up
but if the platform goes too high it stops! it might be a bit jerky but hey! better than nothing (or tweaking)

A possible method is to have a piston connected to a 3-way switch which is controlled by 2 winches on either side set to directional. Put water switches on the platform one facing up and one facing down(inverted) make them both 180 and directonal.

Effect: when the platform goes under the water it will lift up and when it goes above the water it will go down.

Remember: make the piston speed veeeeerrrrrrryyyyyyy slow to stop jolty effect

Hi, thinking the water switch idea isn't really usable because the whole point of using the platform was to connect the fish to it but it shouldn't be viewable by the player! The player just needs to fear the water level rising whilst he scrambles to the top of the shaft avoiding getting snapped at by the fish!

Think I've got the timing down for the platform and water level rising, next problem is what to do about re-spawning if the player gets killed by the fish? Do I try and re-set the water level and fish platform or do I have a moving checkpoint? As this is my first proper level i have no experience in moving a spawn point, is it best to do it on a piston? Thanks to everyone that's tried to help so far!

Pretty much anything can be made invisible. Switches and connectors have a "Visible" option, and see this post (https://lbpcentral.lbp-hub.com/index.php?t=17759-Creating-Editable-Invisible-Material-In-Seconds&p=312921#post312921) for how to make materials invisible.

Having a moving checkpoint is much easier than adding in the logic required to reset a 'puzzle'. Could you attach it with an invisible rod to the same platform which you attached the fish to?

Aya, thank you so much for that link! I had no idea you could make materials invisible, that's amazing! Hopping on to lbp now to try it all out, thanks again and I'll let you know how I get on...2010-08-27 21:26:00
