    Thanks for the quick fix. You might want to consider the elastic reconstitution as part of the demo--it is really impressive to watch shapes rising up out of the sea.

  • Hello Collodium;

    I was using your elastic particle demo (see below for exact code) and I thought I would see what happens when the elastic particle group loses elasticity and melts and then regains it. This works fine for one group (just "tag" or "tag2") and its fun to watch it jump back together.

    However when I do both at once it freezes and sends this message (see below) to the console.

    thanks for your time.

  • Hello;

    Does anyone have any suggestions about an effect I can use to make the collection of particles blend to a liquid look? I think I have seen effects that give a blob of particles more of an edge and smooth out the small gaps in the liquid.

    thanks

  • Colludium;

    Yes, it looks like it is working on the elastic demo and the create particles demo.

    thanks for the fix.

  • Colludium;

    Thanks for the response and the example. Am I looking for a very subtle difference between 1 and 99 solid on and off?. I tried every combination in the example you sent and they all look the same--including leaving solid on and never shutting it down. I also don't see anything in the For the Particles - Create Singles.c3p so I suspect maybe I never did the install correctly. I will try it from scratch on my home computer and see if that makes a difference this evening. I can see other people have gotten the jello-like behavior to work so it must be possible.

    thanks for your time.

  • Colludium;

    I am running your example Particles - Behavior Flags - Elastic.cp3.

    I am trying to get the particle groups to stick together and not flow away by adjusting

    the parameter "particle system elastic strength" a value from 0 to 100 (according to the documentation)

    I only added one line to the example (see below). It does not have any effect if it is 1 or 99.

    Can you explain how I make the block more stiff like a rubber box instead of a liquid?

    (I tried setting spring strength too.)

    (I noticed that Particles - createsingles.c3p does not create any particles I can see)

    thanks for your time

  • Hello;

    How do I set up one of these elastic matrix shapes? Is it body type particle system? When I put a single sprite on the screen, set it as Dynamic and do nothing else it falls with gravity. If I make it a particle system it just sits there.

    If I could get a simple elastic example I would be pleased. All it has to do is fall on the floor and squish a little.

  • in some games the player does "editing" too.

    I have a game where the player builds his ship out of parts. Some of those parts are armor and he wants to know while he is building his ship in game--how much is cosmetic and what is the real pollygon?

    I could make up collision polygon shaped sprites and show that or put image points on pollygon points and draw lines or--you could tell me where the polygom points are.

    There are work arounds--just sometimes you want to know where they are. For me it would not be a high priority--but since you asked thats why.

    yours

    Winkr7

  • I would, sometimes you want to show polly even for the end game user.

    You could put an image point at each polygon point if you need to, but it would be easier to have access.

  • You can try this:

    Make both moving objects solids (disabled) and give them custom movement.

    Check each tic if they overlap and are both moving along the path.

    if so enable one to solid.

    use custom movement push out solid.

    set them both back to disable solid.

    This will make them not overlap but one of them will have to wait while the other moves along the path if you want to get tricky you can give one of them priority and use push out solid on the other non priority one.

    I hope this is useful.
