often it is really helpful to look into their code[21:23:49] <ChaseWaylon> act(Math.min(Gdx.graphics.getDeltaTime(), 1 / 30f));[21:23:53] <X-Ray-Jin> yea[21:25:17] <ChaseWaylon> so why would one have stage.act(Gdx.graphics.getDeltaTime()); ?[21:25:29] <ChaseWaylon> instead of stage.act();[21:25:55] <ChaseWaylon> i guess i pasted it from some tutorial without thinking about it[21:27:15] <X-Ray-Jin> well you can just use it again at this point it really depends what your game is about[21:27:26] <X-Ray-Jin> and how you want the game to consider time passed[21:28:38] <ChaseWaylon> i want precise animations :)[21:29:05] <X-Ray-Jin> for sp games you can very well go with act() as the one player would be the only one who has to wait for his game to update so he basically doesnt care how much time went by so capping at 1/30 is nice in that way tha it might be unplayable if 2s pass from frame to frame[21:29:10] <ChaseWaylon> with movement speed independent from famerate[21:29:30] <X-Ray-Jin> that you have to go with delta and multiply all your movement by that[21:30:00] <ChaseWaylon> what, like manually?[21:30:28] <X-Ray-Jin> in mp games for example it would be very bad when a player calculates its steps with 1/30 even if it takes longer to calculate a step. you would be out of sync very fast[21:31:00] <X-Ray-Jin> actions i think consider it automatically[21:32:06] <X-Ray-Jin> actually forget that: (9:29:31 PM) X-Ray-Jin: that you have to go with delta and multiply all your movement by that[21:32:15] <X-Ray-Jin> thats true for act() too[21:35:16] <X-Ray-Jin> so you said you want precise animations. that is unrelated to calling act(delta) or act() you faced the issue because of your loading. that makes the delta in a frame so high that all the delays were triggered at once when checkd. if the game tells your actions 1s passed and you want to have .1 .3 .2 delay than the condition is met for all of them in the same frame[21:37:52] <X-Ray-Jin> the precision of your animation is directly related to delta ... the smaller delta the more precise[21:38:08] <ChaseWaylon> so it can happen anytime? some device activity in the background can push my actors out of sync?[21:38:24] <X-Ray-Jin> well yea[21:38:27] <X-Ray-Jin> as in any game[21:38:33] <X-Ray-Jin> its lag what we are talking about[21:39:08] <X-Ray-Jin> if you game doesnt have enough resources to maintain small enough deltas ie high enough fps you face all of these problems[21:39:26] <ChaseWaylon> hmmm lag is more like stuttering, not game graphics sticking together :)[21:39:49] <X-Ray-Jin> but nowadays you probaly you own biggest enemy when speaking of performance in ur update loop[21:40:38] <X-Ray-Jin> yea but it is a side effect[21:40:57] <ChaseWaylon> so if I test on older device and its fine, then its fine, right?[21:41:05] <X-Ray-Jin> the stuttering is just the graphics of a game lagging[21:41:16] <X-Ray-Jin> but it has all kinds of effects in the logic[21:41:23] <X-Ray-Jin> depending on the implementation[21:41:43] <X-Ray-Jin> if you using box2d for example you will experienced a lot of wrong collision detection when frames drops[21:42:14] <ChaseWaylon> that sounds really terrible[21:42:28] <X-Ray-Jin> yea well.. thats game development[21:42:30] <X-Ray-Jin> ^^[21:43:44] <X-Ray-Jin> (9:40:57 PM) ChaseWaylon: so if I test on older device and its fine, then its fine, right?[21:43:44] <X-Ray-Jin> hmm not really but for the most parts i guess you can consider that[21:44:26] <X-Ray-Jin> what i have learned is never say its running on a device or system if you didnt test it in advance...[21:45:14] <ChaseWaylon> oh well.. no way back now :)[21:46:03] <ChaseWaylon> flash pro was so easy :))[21:46:21] <X-Ray-Jin> ^^ but also very limited[21:46:39] <ChaseWaylon> thats why i am going through all this pain[21:48:27] <ChaseWaylon> hey, thanks for the help, when i learn enough, i will help you :)[21:48:49] <X-Ray-Jin> sure, np. i appreciate that ^^[21:49:08] <X-Ray-Jin> rather help other beginners that are where you were before[21:49:12] <X-Ray-Jin> :)[21:49:41] <ChaseWaylon> yeah, that would be better :))[21:49:59] <X-Ray-Jin> belive me no matter how far or not you are there are always people who are even more beginner[21:51:11] <ChaseWaylon> maybe. though I am yet to see a question here which I could answer[21:51:38] <X-Ray-Jin> oh no worry they come faster as you might think[21:53:04] <X-Ray-Jin> just hang around here for a while[21:54:32] <ChaseWaylon> well it's not like I will suddenly learn everything and go away[21:54:52] <X-Ray-Jin> :) i guess[21:55:03] <X-Ray-Jin> too much to learn in this field[21:55:21] *** isdera <isdera!~isdera@cpe-74-78-187-102.maine.res.rr.com> has joined #libgdx[21:56:18] <X-Ray-Jin> didnt mean it offensive just you know like give it a little time and pay attention to the chat and i bet you ll have something to answer within a week or somethin^^[21:57:28] <ChaseWaylon> :)[22:04:55] <wp_> How do i fix this?[22:04:56] <wp_> Incompatible HAX module version 3,requires minimum version 4[22:04:56] <wp_> No accelerator found.[22:04:56] <wp_> failed to initialize HAX: Invalid argument[22:08:43] <isdera> upgrade your hax module[22:13:42] <bomb> upgrade your fax modem[22:19:44] *** royal_screwup21 <royal_screwup21!89de72f6@gateway/web/cgi-irc/kiwiirc.com/ip.137.222.114.246> has joined #libgdx[22:21:00] <royal_screwup21> I'm trying to create a robot that moves left and right.
