| Summary | 0017881: Shot Rotation (engine feature) | ||||
| Description | I've been messing around with shot modding - cool engine btw -- but haven't come across this feature, yet. Maybe it's already there, I could be wrong but... shot rotation? I imagine you would have 2 variables. RotationDirection(clockwise or counterclockwise) and RotationSpeed (a number, heh) which would allow the shots to rotate at a specific speed. This could really increase the variety of shots that could be created and add a little pizzazz without requiring art assets. For example, create a star shot, add rotation, and now you have the shuriken shot. Just an idea, apologies if this is super unfeasible or already in the engine and I've missed it. | ||||

It is kind of already there. I think you're looking for: <change angle="200" time="1" /> I'm going off of TLF's bullet file, but the SR ones look like they've gained features, not lost, so that should work. The time is the delay, and the angle is the final value. |
|
|
It's already there!? Cool, I'll check this out later, ta. |
|
|
"Change angle" actually changes the trajectory though, I think he means just changing the direction it APPEARS to be pointing in? I would definitely support something like that. Some other effects that are just "visual" to add to the engine for bullets would be nice as well. |
|
|
Oh! You're right. And yes l that would be a neat feature. |
|
|
Yeah, I meant rotatable appearance of the sprite. Something like this would really open up a lot of possibilities for the bullet visuals. To be clearer: specifically I was thinking that you set a speed and direction, and as soon as the bullet is spawned it begins rotating that way, giving the illusion of a spinning projectile. |
|

Setting a rotation on the appearance of the sprite has more to do with the bullet entity itself (defined in CMP_Bullets) versus the bullet pattern. Most of the xml stuff from here can apply to bullet entieis, which you can rename as desired. Note how shots are able to use a different image name from their entity name, thus allowing one graphic to be used for multiple shot definitions: <entity name="ShotSludgeFire" category="Shot" shader="Additive" draws_below_others="true" image_name="ShotSludge"> <hitbox radius="22" /> </entity> I've not tested this, but I imagine it would work: <entity name="BulletDoubleTriYellowSpinner" category="Shot" passive_rotation_speed="6" image_name="BulletDoubleTriYellow" > <hitbox radius="8" /> </entity> That uses the passitve rotation thing as defined here: https://arcengames.com/mediawiki/index.php?title=Starward_Rogue:XML_-_GameEntity_Definitions If that doesn't work, then please do let me know. But it shouldn't have any gameplay effect; just graphical, as you're requesting. :) |

I tried testing this, and it doesn't seem to work, although I could be wrong since my understanding of the system is quite limited. That passive_rotation_speed variable is listed in the AI-only section and I was using it for a player weapon so maybe that's why? |
|
|
Next build you can use this: - added to bullet: *non_sim_rotation_speed_rand_min (float), non_sim_rotation_speed_rand_max (float) **For each NonSim-only entity spawned by this definition, applies an ongoing rand(min,max) degrees-per-second rotation. Thanks! |

Anybody got any examples on how this new bullet spinning code is meant to be written? I haven't been able to get it working, yet. Usually if I'm not sure how something works I can just look at one of the other examples of it in game, but nobody seems to have used this feature so far. |
|
|
I actually had forgotten this was there... I'm guessing that this goes either in the initial defining bit for the bullet (the bit that actually has "bullet" written in it) or if not that, in the "change" command. I cant think of any other way this would really function. I'll try to remember it's there and mess with it later tonight. |
|
|
Tried it out, using it as described in the XML documentation, and it doesnt appear to be working. Doesnt do anything at all. Is there something I'm missing? I'll admit I still dont really understand this "non-sim" thing, so that might be part of it. |
|
|
I've made spinning bullets, but it was ugly. I use <change angle> in combination with <change location> inside of a loop. Having the graphic be independent of the actual shots direction would be nice. I haven't tried the sim_rotation yet to see if it works. I'm searching past mantis entries for beam weapon notes. |
