johnnyboy 3797 Posted May 15, 2017 I need to script underwater bubbles, and underwater blood. For a marine salvage mission, I want player to attach simulated inflatable objects to a sunken wreck, and inflate them to raise the wreck. This inflation should generate a lot of bubble effects. I also want to create blood underwater on demand. This would be the same blood you see when you shoot a unit under water. Any help is appreciated! Share this post Link to post Share on other sites

johnnyboy 3797 Posted May 16, 2017 Wow, perfect. Thanks much for the bloomin' bubbles and bloody blood! I owe you a couple pints mate. Maybe you could educate me a bit on this...When I read the two scripts, I don't see a parameter saying "bubbles" or "blood". How does Universal translate into these entirely different looking particles? How did you find these...experimentation? 1 Share this post Link to post Share on other sites

HallyG 239 Posted May 16, 2017 cfgCloudlets in the config viewer. It displays the particle parameters for most of the particles used in the game. Some of the parameters can have a formula (similar to the one in TAG_fnc_BLOOD) which alter some of the parameters passed upon the arguments provided. Added to that it involves some experiment in the editor by changing their random velocities, rotation and stuff. I think it creates a generic particle and just changes its colour (including transparency), velocity and more. So for example a 'blood' particle is darker, more opaque and heavier than a 'bubble' particle. I'd post links to the wiki pages but I'm not at my computer right now. Haha, I can't say but it's fairly out there (I feel like constant studying for my finals has added to its absurdity..) 3 Share this post Link to post Share on other sites

So if you use: (getPosATL player) vectorAdd [0,0, HEIGHT ABOVE SEA FLOOR] As the first argument it should be fine Hey, i am fairly new to scripting, where would I put these sections in? init.sqf ? And "(getPosATL player) vectorAdd [0,0, HEIGHT ABOVE SEA FLOOR]" on the player? (Assuming this still works after 4 years) Share this post Link to post Share on other sites
