c# - Slow, sweeping turns instead of instantly facing the target -

-

I have a code to face a goal and move on to it: 

 < Code> var X: number = _targetPosition.value.x - _position.value.x; Var y: number = _targetPosition.value.y - _position.value.y; Var Target Angel: Number = Mathematics.Tan 2 (Y, X); _angle.value = targetAngle; _velocity.valuestxe (mathematics (target angle) * 90, math sin (target angle) * 90);   
 I would rather say a frame instead of a two degree (or quarter radian or whatever you want to use, I can convert it anyway)? Its goal may be increasing, so I can not use the formula that takes time to meditate ... instead of snaping it should be changed to a frame of X degree.  
 In addition to this, if you can show me how to apply this rotation takes into account a delta time which would be great, but I can try to understand it.  
 Thank you!   
 
 
 Unless you are compelled to run your program at a fixed time, Even the algorithm which fails to pass the time, is likely to be wrong. Depending on the hardware, framerates may vary wildly; A solution that works on 80 fps on your computer, is not running on the same, which is running at 200 FPS at Supersuper's $ 5000 Alienware.  
 You need to calculate the difference between the current angle of the object and its target angle, then increase the angle with some amount depending on the difference between those two angles, passing through the previous frame. The time will be multiplied by the time.  
 Consider the following (untested code above my head):  
  // Find the difference in angles, always at least the movement var target = Math Moving in direction .atan2 (x, y); Var difference = target - _angle.value; If (difference> Math.PI) {difference = ((2 * Math. PI) - difference); } If (difference <-Math.PI) {difference = ((2 * Math.PI) + difference); } // Move the character rotation to a set amount of time per unit in var delta = (difference <0)? -Rotation change seconds: Rotation change seconds; _angle.value + = Delta * game time ElapsedGameTimeCollus;   
 Whether the goal is running or not is irrelevant. The question you are asking with this code says, "Where is the target  where  and what do I have to face it?" If the position of the goal changes in the later frame, the direction in which you need to move will also change, and the object is moving in the opposite direction, as I believe you intend.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

c# - Using Vici cool Storage with monodroid -

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered. Especially when trying to connect like the example for Mono Touch string dbName = path. Cobain (environment. Gatefolder path (environment specialfolder personal), "mydb.db3"); // The following line will be called coolestation, where is the database, // to make it if it does not exist, and call a delegate that creates the necessary tables (only when the database file was newly created //) CSConfig.SetDB (DbName, true, () => {CSDatabase.ExecuteNonQuery ("Subscriber Integer Primary Key Attribute, Name Text (50) No, Number, Date First Text (30)");); There is no difference when I try to use the methods of CSConfig and when I cscfif If I try to pass 3 aggregates to STDB (3) then I get the invalid ...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
