HEAT, RADIATION and OXYGEN 101 - ALPHA 6.0 NOTE: All of this is subject to change. So be warned, if you encounter problems in space because following this guide, I am not held responsible! Here is a link to the Official Alpha 6.0 FAQ: http://empyriononline.com/threads/read-first-alpha-6-0-gameplay-faq.10344/ ------------------------------------------------------------------------------------------ We have to build our ships differently than before. We need to make sure we are not putting any heat sources too close to our living space and that our ships are airtight to hold the oxygen in and the harsh environment out. Lets talk about heat first. ------------------------------------------------------------------------------------------ HEAT AND RADIATION Heat (and radiation) can be a problem if you are not planning your ship around it. Keep the heat sources away from the places you are walking and especially away from the places you might want to stop for a while (constructors etc.). Depending of the ship size, its probably a good idea to build separate compartments for the worst heat sources. The way heat and radiation work is basically the same. On how to read the different heat numbers on your HUD and how to protect yourself against them, check my other guide: http://empyriononline.com/threads/guide-surviving-in-space-101-experimental-6-0.10422/ Here are the some of examples heat and radiation sources. NOTE! These are just examples of some the item types, general consensus is THE BIGGER THE ITEM - MORE HEAT & RADIATION IT EMITS! WARP CORE - LOT OF HEAT and RADIATION. GRAVITY GENERATOR - Some HEAT and RADIATION. This is not too bad, you can get away this being in a corner or alongside corridor somewhere. Just not in a place where you need to stop a lot. GENERATOR - LOT OF HEAT THRUSTERS - MASSIVE AMOUNT OF HEAT and some RADIATION. FUEL TANKS - Little RADIATION. If you wear light armour, you'll be fine. Much smaller than for example radiation level in Omicron (3.5) WARP FUEL TANK - Some HEAT and RADIATION. Medium armor is enough to protect. GROWTH LIGHT - Some HEAT. Medium armor is enough to protect. So atleast these things you want to keep away from your living quarters! Heat/radiation is emitted ONE BLOCK away. Walls itself don't block heat/radiation, but they of course create space between the heat source and you. OXYGENATED VESSELS AND BASES Lets go step by step what you need to make your vessel to be OXYGENATED. When oxygenated, you can take off your helmet in your vessel and use the O2 in your vessel oxygen tanks rather than use up your suit oxygen. You have the 02 symbol in the hud telling you have oxygen to breath in. All vessels and bases can be oxygenated (SV, HV, CV and BA). !!! AIRTIGHT !!! Your vessel has to be airtight in order for you to have it oxygenated. Your vessel also needs to be airtight (but not necessarily oxygented) in order for you to be protected from the outside environment. When airtight, inside temperature is 22 celsius all around (apart from possible hot spots from your own equipment) and thus protecting you for example from the coldness of space. Vessel also needs to be powered (radiation protection will work even if not powered). What does airtight mean? Let's talk about it next. 1. MAKE THE SHIP/BASE AIRTIGHT! To hold the oxygen in and the harsh environment out. This can be tricky as we are not used to building like this. If you notice that after you've setup everything, you only have air right next to ventilators, you probably have a leak somewhere. You can press (and hold) N and click on the Oxygen tab for visible information about he oxygen flow. From the same menu you can access the airtight block view which might help you hunt down holes. If you have problems, my tip is to seal of parts of the ship and try to find the area with the leak that way by eliminating parts of the ship with walls. You might need some extra ventilators for testing. You can keep the ventilators/oxygenation ON, if you manage to make ship or parts of it airtight, air will start to flow. You will note this by the O2 symbol in your hud all around the ship. Important - Also remember that air needs free block space (or a block space with non-airtight block in it) in order to flow. Too narrow builds might block the airflow - as a block space is either airtight or not. Orientation of the block itself doesn't matter. For example if you have a window - air will not flow past that block, no matter which direction the window is facing. Hunting for leaks can be difficult and time consuming and I recommend spawning the ship in creative and take a closer look there. Some things that are NOT airtight: -LCD Screens -Some doors (the ones without blue forcefields) -Ramps -Shutter window (transparent version) -CV weapons -Oxygen and Fuel Tanks -Cargo Box 2 and 3 -!!!GROUND!!! (always check the floor!) ... and so on. LifPizzas has done really helpful video regarding the different non-airtight/airtight blocks and good tips regarding oxygenated rooms in general: You only know whether your ship is airtight for sure after going thru all the rest of the steps. You think you've got your ship airtight, move to the next phase. 2. ADD VENTILATORS This is the new block. This will provide air to your base or vessel. Make sure atleast one of its sides is unblocked towards the room/area you want oxygenated so it can provide air. When building notice that airtight doors can also work against you! They will cut out the air supply to the other room so you will have to make sure you have ventilators in each different area of the ship or base. If you only have one area that is all connected, one ventilator should be enough. Multiple ventilators and divided compartments have of course their uses - it will be more robust against damage as one hole won't bring the whole vessel oxygen system down. Blue forcefield will tell you whether the door is airtight or not. Note that vessel needs to be powered in order for it to be visible. This door leads to outside, so we want to make sure its airtight. 3. OXYGEN TANKS Add oxygen tanks. Add Oxygen. This can be done easily via the new interface which connects ALL the tanks. Make sure you have enough, you can see how much air you need in the control panel. 4. TURN ON THE OXYGEN Go to the Control Panel (P) and click on the "O2" checkbox in order to turn on the oxygen supply. You're done! You should have air in your ship now. ...and if not, go back to step one and try again. It might need some trial and error. One thing to note in the Control Panel, it also shows your oxygen: -How much 02 you need for to oxygenate the vessel -Total how much oxygen you have in your tanks -Current 02 in base use So be sure you have enough oxygen to oxygenate your base vessel. If not, add more 02 tanks/more oxygen and fill them with oxygen. !!! WARNING !!! Safe way to turn off oxygen is clicking on the 'O2' switch in control panel. That way the oxygen will return to the tanks. DO NOT TURN OFF VENTILATORS MANUALLY BEFORE YOU HAVE TURNED OFF 'O2'. If you do this - you will lose all the air currently in the base/vessel. - - - - - - - - So thats it - have fun in space and be safe! Don't try to cut corners when building, build smart so you dont have to fix them later! Hope this helps and if you have any questions or the guide seems to be missing something let me know.
