Help Cloth to simulate slime

[josemendez]

Hi, thanks for the reply. Just purchased Obi cloth. 

I'm trying to create a slime simulation game. This is the reference game. Have a few questions regarding the same:

1. Can a soft body cloth surface I make react to user's finger touch as shown in reference? If so, can it create a "hole" in the shape of a finger when pressed on? 

2. Also, does the cloth surface allow mixing of colours on runtime? The reference game I showed also has a feature where a colour can be gradually mixed onto the slime using user's finger.

3. How do I turn gravity off for the cloth? I want it to react to touches and behave like a slimy fluid, without falling down due to gravity. (As if the cloth is actually a slime fluid kept in a bowl) I read the manual but didn't get a clear picture.

1.- Yes, it is up to you to implement such system. You have access to particle positions/velocities, you should simply modify them when the user presses the screen. Use Unity's input system to achieve this, in conjunction with Obi's particle getters/setters:

2.- This has nothing to do with the physics engine/cloth simulator, as it is some sort of "paint" mode. It is completely up to you to implement this. The cloth mesh is a regular Unity mesh, to achieve this you could use per vertex colors, or textures combined with a custom shader.

3.- Simply reduce the solver's "gravity" to zero. See:
