Execution order within the Update() loop method in Unity3D

孤街醉人 提交于 2019-12-06 06:19:48
I'm trying to find the appropriate words to use to describe the issue that I am having, hopefully this will explain the problem. I have two Update() methods in two different classes, and some of the functionality in one is reliant on data from another. Code A is reliant on Code B's data, using Debug.Log() I found that Code B's Update() is being executed after Code A's Update() . My question is, Is there a out of box method to controller the Call stack of the Update method? If there is how is it done? If there isn't, does anyone have any technique that I could employ to resolve the problem. I

Ford-Fulkerson algorithm with “weighted” edges

隐身守侯 提交于 2019-12-06 06:11:17
问题 Is there any variation of the Ford-Fulkerson that adds an extra dimension of "weight" to the edges? By that, I mean some edges are more ideal than others, and while all the possibilities are there, it will prioritize the ideal edges over the lesser ideal edges. 回答1: There are two common generalisations that I know of to add weights. Min cost flow Suppose you had a weight for each edge and wanted to compute the flow that satisfied the constraints and had minimum cost. (Cost = sum of weight *

If statement and assiging wires in Verilog

删除回忆录丶 提交于 2019-12-06 03:17:00
New to Verilog and trying to figure out the basics of assiging wires based on combination logic. I have: wire val; wire x; wire a; wire b; always @* begin if(val == 00) I want to assign x = a if(val == 01) I want to assign x = b end where a and b are wires with values - and x is a wire going into a register. If you can please point me in the right direction to what I need to change, it would be much appreciated. Thank You. First thing to ask is: are you trying to use those wires as inputs? Or are you using those as connections? Second thing: Do you want a synthesizable code? And you cant

Need to create a “choose your own adventure” type guide - best approach to use

问题 Basically need to ask user a set of questions and gather information along the way. Each question could have impacts on different questions down the road. Another example would be turbo tax's web interface, answering yes on some ?s may trigger future questions. Seems like this would be a fairly common problem in software so I guess I'm asking if there are any existing solutions/Design Patterns out there that could help. Kind of seems like a state machine, but I think that is an

Using a TextWatcher on a EditText to calculate the total and sum total in real time in android?

Here i want to take the default value coming from my database and setText to that value and calculate the net rate and total or else if the user edits the rate or making charges i would like to calculate the net rate and total based on that value in real time. This is my code for calculating and displaying the values. private void showItem(String json) { String itembarcode = ""; String itemdesc = ""; String weight = ""; String rate = ""; String making = ""; double wt = 0.0d; double rt = 0.0d; double mk = 0.0d; try { JSONObject jsonObject = new JSONObject(json); JSONArray result = jsonObject

As you know this alarm bug , "We're aware of an issue related to nonrepeating alarms set for January 1 or 2. Customers can set recurring alarms for those dates and all alarms will work properly beginning January 3." Read more: http://news.cnet.com/8301-13579_3-20026911-37.html#ixzz19temSRs9 I just wonder why it is just related to 2011/1/1 and 2011/1/2 but not other day? 来源: https://stackoverflow.com/questions/4579360/which-kind-of-bug-cause-the-ios-4-alarm-failed

Is any one who can help me to create PHP or mysql Code for our Office employee salary tax table. Here is the base for our tax regulation. If salary is >= 0 and <= 150 it will be 0% (Nill), If salary is >= 151 and <= 650 it will be 10% - 15.00, If salary is >= 651 and <= 1400 it will be 15% - 47.50, If salary is >= 1401 and <= 2350 it will be 20% -117.50, If salary is >= 2351 and <= 3550 it will be 25% - 235.00, If salary is >= 3551 and <= 5000 it will be 30% - 412.5, If salary is >= 5001 it will be 35% - 662.50 function get_taxed_salary($salary){ if ($salary <= 150 ){ return $salary; }; if (

问题 I would like to know some solutions to such a problem. It is given a number lets say 16 and you have to arrange a matrix this way 1 2 3 4 12 13 14 5 11 16 15 6 10 9 8 7 the language doesn't matter, (preferably PHP); 回答1: [EDIT: Update] If language doesn't matter: Go to: http://rosettacode.org/wiki/Spiral_matrix In PHP: Here you go: <?php function getSpiralArray($n) { $pos = 0; $count = $n; $value = -$n; $sum = -1; do { $value = -1 * $value / $n; for ($i = 0; $i < $count; $i++) { $sum +=

Kripke semantics: learning software available?

女生的网名这么多〃 提交于 2019-12-05 16:42:45
I am stuck on Kripke semantics , and wonder if there is educational software through which I can test equivalence of statements etc, since Im starting to think its easier to learn by example (even if on abstract variables). I will use ☐A to write necessarily A ♢A for possibly A do ☐true, ☐false, ♢true, ♢false evaluate to values, if so what values or kinds of values from what set ({true, false} or perhaps {necessary,possibly})? [1] I think I read all Kripke models use the duality axiom : (☐A)->(¬♢¬A) i.e. if its necessary to paytax then its not allowed to not paytax (irrespective of wheither

Anyway to shorten if ( i == x || i == y)?

半城伤御伤魂 提交于 2019-12-05 16:12:43
I tried to shorten my code, from : if(i== x || i == y || i == z ) to if (i == ( x || y || z )) I know this way is wrong because I got incorrect i in log. However, is there any method to shorten the code in objective-C ? if there is a higher probability that x==i than y==i then it's better to write it as x==i || y==i as opposed to y==i || x==i because if the first statement evaluates to true, the second one is not evaluated (it's shortcircuited) You could use a switch statement, but that doesn't really buy you a lot with only 2-3 values. switch (i) { case x: case y: case z: ....some code....
