Current engulfment , membrane generation and Hitbox: ![ss](https://thrivecommunity-uploads.b-cdn.net/original/2X/4/4102d4d01f6a24ce7110abdbec34111ff5c72a6d.jpeg) Based solely on size, it’s still too rough. More consideration should be given to cell shape. > [@Cell size with Nuclear grade and Maintain shape Consumption](https://community.revolutionarygamesstudio.com/t/cell-size-with-nuclear-grade-and-maintain-shape-consumption/6318/3): > > [By the way, I think EngulfSize can be further refined into EngulfAbility and EngulfResistance. Compare the EngulfAbility of the devourer with the EngulfResistance targets .

There is an anaerobic chemical process which uses iron to breakdown glucose, releasing a reduced form of... According to the data I have consulted, iron respiration (not the Chemosynthesis with oxygen to iron oxide in the game now. Why does the nature have pure iron, and shouldn’t the reducing agent be Fe2+ ?) is an extracellar respiration, because Fe3+mainly exists in the form of solid precipitation, which means that it is unrealistic for cells to collect and store Fe3+. Fe3+ can be used as an environmental compound and its concentration can affect the rate of iron respiration. But this homogenizes with oxygen, and the gameplay is too monotonous. (NO3- can do this directly because it participates in the Nitrogen cycle as a play method) Considering that Fe3+has a certain solubility and mainly exists in the form of solid precipitation, its concentration can be unevenly distributed within the region. In the current game, there are iron blocks (the red ones should look like Fe (OH) 3 precipitates). If there are Fe (OH) 3 precipitates, a decreasing Fe3+concentration will be distributed around them. This concentration can be opened by the chemical receptor to the Fe3+concentration field, unlocking the tendency of AI towards Fe3+behavior. ![Fe3+](https://thrivecommunity-uploads.b-cdn.net/original/2X/8/8dd524f9863dec55a43c02e310fa5593d9fb529e.jpeg) * * * > **[Surface Area, Volume, and Ratios](https://forum.revolutionarygamesstudio.com/t/surface-area-volume-and-ratios/978/6)** > > Woe is me for speed-reading, I’m sorry about that. Reading through the original post again I see that you’ve already gone over the importance of surface area and all that. Fair enough. Thinking on this more though, I feel it’s at risk of... I would like to know if there is a corresponding embodiment of this surface adjacency bonds in reality. I like this design, perhaps it will encourage cells to wrinkle. Based on the knowledge I have, if Surface-adjacency bonuses come from adjacent cell membranes, those biochemical reactions that rely on membrane structure should benefit, especially utilizing ATP synthesis for oxidative physiology. Also, will external structures such as flagella affect the Surface-adjacency bonuses of internal structures? They do not affect the internal structure and cell membrane proximity. A simple and intuitive method for calculating surface area is good and easy to understand. However, when calculating surface area and exposure, it is required that this is also the exposure of the entire cell. Otherwise, players may design a spring, cavity or fishbone. Perhaps it is necessary to use membrane generation for tuning? ![spring](https://thrivecommunity-uploads.b-cdn.net/original/2X/e/e1db821d6bfd9e3a18786d0590589d10946503b5.jpeg) One problem is that if the part placement mechanical is added, the existing Organelle replication mechanism will have a greater impact on cell design. The newly copied Organelle will appear outside the cell and destroy the original Surface-adjacency bonuses. --- _[View the full topic](https://community.revolutionarygamesstudio.com/t/comments-on-specific-development-forum-posts/5150)._
