How would I go about changing the registration point of a movieclip labeled "tablet" placed on the stage (root) dynamically?
For example: I have the following:
var tablet = this.tablet; //movieclip labeled "tablet" on stage
function resetTablet(){
tablet.regX = tablet.width/2; //move registration point to center
tablet.regY = tablet.height/2;
}
However when I call it using GSAP:
var tl = new TimelineLite();
tl.to(tablet, 1, {alpha:1, onComplete:resetTablet})
.to(tablet, 3, {alpha:0, scaleX:1.5, scaleY:1.5})
the registration point is still set to the upper left corner rather than the center.
What am I doing wrong here? Thanks!
Registration points affect change both the transformation point, but also the position. If you set a displayobject that is 100x100 pixels to regX=50;regY=50, then it will draw from that point, moving the content 50px to the top and left. If you make that change you should also translate the clip to x=50;y=50.
An issue with you example is that there is no width or height on EaselJS content (explained here). You can get the bounds of anything generated by Flash CC using the nominalBounds property, which Flash exports as a property on every object. If you have multiple frames, you can turn on "multi-frame bounds" in the publish settings, and a frameBounds property is added to the objects as well.
Note that nominalBounds and frameBounds are not used by the getBounds method.
Here is how you might be able to approach it.
var bounds = tablet.nominalBounds;
tablet.regX = bounds.width/2;
tablet.regY = bounds.height/2;
// Optional if your actual registration point was [0,0] before:
tablet.x += tablet.regX;
tablet.y += tablet.regX;
Hope that helps.

I have a noUiSlider with several handles to allow specifying several contiguous date periods (example = Feb to Apr, May to July, and Aug to Sept). Ideally I would like to have labels that appear centered on the connect divisions to describe what each period relates to (ex. "Current Period", "Next Period"). I was thinking I could do this by setting a centered background image on the noUi-connect divisions.
However, the noUi-connect divisions use transform (translate/scale) styling which results in my background images being scaled which I do not want.
I also thought maybe I could revise the javascript to generate an outer division around each nonUi-connect division, and I would apply the background onto the outer division instead - but I was unable to get the background from the outer division to appear.
Any other ways I could accomplish this? The only other thing I can think of it to have floating divisions defined outside of the noUiSlider object which I would need to reposition whenever I detect changes in the handle positions.
You can add an element outside of the connects and absolutely position it.
A quick version for a slider with two handles (showing the value for the first handle):
var origin = slider.querySelector('.noUi-connects');
var node = document.createElement('div');
node.style.textAlign = 'center';
node.style.position = 'absolute';
node.style.zIndex = '10';
node.style.fontSize = '10px';
origin.appendChild(node);
slider.noUiSlider.on('update', function(values, handle, unencoded, tap, positions) {
node.style.left = positions[0] + '%';
node.style.right = (100 - positions[1]) + '%';
node.innerText = values[0];
});
Just realized another approach is to set the innerHtml of the specific noUi-connect divisions to my label values. Simpler than playing with background images.
But the transform styling still affects the labels, so the end result is not better. Maybe I can load the innerHtml with an inner division that somehow ignores the transform settings but I haven't figure out how to do that yet. transform: none does not make any difference.
I created a new path2d following the instructions in the my first game article: http://docs.godotengine.org/en/3.0/getting_started/step_by_step/your_first_game.html
I wanted to move the "box" on screen so that I could see how the mobs spawn in, but when I ran the scene, it stayed off screen.
I created a new path2d, centered this one in the middle of the screen, and it works like I wanted it to, but now I moving this one in the editor doesn't update the position in game.
What's going on?
Thanks
func _on_mobtimer_timeout():
$mobtimer.wait_time = 0.1 + randf() / 2
$mobspawn/moblocation.set_offset(randi())
var mob = Mob.instance()
add_child(mob)
var direction = $mobspawn/moblocation.rotation + PI/2
mob.position = $mobspawn/moblocation.position
direction += rand_range(-PI/8, PI/8)
mob.rotation = direction
mob.set_linear_velocity(Vector2(rand_range(200, 200 + score * 30), 0).rotated(direction))
A Node2D's position property is relative to it's parent's position. The code from the Dodge The Creeps tutorial assumes that MobPath is located at 0, 0 and fails when that assumption is false.
In your case you are taking a MobSpawnLocation's position relative to MobPath and then setting it as the new Mob's global position.
Luckily Node2D's have another property that we can use in these circumstances global_position. It can be used like this:
mob.position = $mobspawn/moblocation.global_position
http://docs.godotengine.org/en/stable/classes/class_node2d.html#member-variables
This isn't a full solution, but I found a weird workaround. Instead of changing the position in the editor, if you use the nodes on the orange box (at the intersection of orange and blue), you can kind of alternate to move the box around.
How to add text below/above in the middle of the polyline in osmdroid? setTitle() does not work neither is setSubDescription().
And also how to add button overlays.
There is a way to do it and it's an opt in feature of the Marker class. The easiest way to find an example is with the LatLonGridOverlay. I'll reduce the logic to something simple to understand below. The key is the order of code, see the title, then set the icon to null, then add to the map. You'll have to figure out where you want the Marker to be based on the coordinates of the polyline but it does work.
Polyline p = new Polyline();
List<GeoPoint> pts = new ArrayList<GeoPoint>();
//add your points here
p.setPoints(pts);
//add to map
Marker m = new Marker(mapView);
m.setTitle("Some text here");
//must set the icon last
m.setIcon(null);
m.setPosition(new GeoPoint(marker location here));
//add to map
source
Setting icon to null alone doesn't worked for me, I need to use setTextIcon:
distanceMarker = new Marker(mapView);
distanceMarker.setIcon(null);
distanceMarker.setTextIcon(distance);
GeoPoint p3 = new GeoPoint((loc.getLatitude()+poi.getLat())/2,(loc.getLongitude()+poi.getLon())/2);
distanceMarker.setPosition(p3);
mapView.getOverlayManager().add(distanceMarker);
There is a too long, didn't read version down below.
So I've been making a little game in which the player has to click on a grid of bricks that matches the color of the needed brick in the upper right hand corner of the screen. After they click on the needed color, the bricks explode and the bricks of the same color next to them explode as well creating combos. That leaves holes in the grid so I have to somehow reset the grid itself without resetting the gamestate itself. I've got something working right now which is this:
private function ResetNow():Void
{
if (Restter == 1) Restter = 0;
//if this block is up here, same results
/*
wantedBricks.kill();
wantedBrik._changeColor = FlxMath.rand(0, 2);
bricks.autoReviveMembers = true;
bricks.revive();
*/
Restter = 0;
//Removes stray detectors so the neverending combo bug won't occur
for (stray in dets.members) stray.kill();
if (Restter == 0)
{
wantedBricks.kill();
wantedBrik._changeColor = FlxMath.rand(0, 2);
bricks.autoReviveMembers = true;
bricks.revive();
wantedBricks.autoReviveMembers = true;
wantedBricks.revive();
for (zgem in bricks.members) zgem.EQUITYCHECK = FlxMath.rand(0, 2);
}
//add(bricks);
Restter = 1;
}
So, again, I have a grid of blocks set up at create, that is group bricks. And I have a sprite in the upper right corner which is wantedBrik. What happens during gameplay, is the player clicks on the bricks that matches the wanted bricks to clear them out of the grid. When there are no more wantedBricks(a group), it is supposed to reset the grid, and change the color of the wantedBrik. I also have it somewhere else in the code that if a member of the big grid's EQUITYCHECK(basic object hacked in value) is equal to the wantedBrik, add it to the wantedBricks(which, is why I'm checking for no more of them). So, what happens?
Well, if the color of the wantedBrik doesn't change, everything's fine and resets like normal. the wantedBricks group acurately counts the bricks that actually match the wantedBrik's color. And when it does change, for some reason, gameplay is normal. BUT, wantedBricks not only thinks that the old color is still needed, but it also thinks the new color is still needed too. So when the player clicks the new needed color bricks, they do explode, but because wantedBrik thinks the old color is still wanted, it doesn't hit null and the grid won't reset.
What can I do to make sure that wantedBricks behaves correctly after a color change?
TL;DR version: I need to get a Haxe array to forget or lose old numbers. How can I do this?
The "Pirate Pig" sample may be useful to you. Since it is a puzzle game, there may be some similar problems that were solved there. You can find it using openfl create or nme create depending on which you are currently using.
You can create a simple array like this:
var myArray = [];
You can also type arrays, like this:
var numbers = new Array<Float>();
Then you can use push(), concat() and other array methods.
I found this solution.
If type of chart is pie, how specify parameters (x,y) of highlight(x, y)?
Thanks
Sorry for my bad English.
Unfortunately, flot doesn't expose the pie highlighting code to the user. So we are pretty much out of luck, but what may work for you is synthesizing a click event at the appropriate place on the page:
$("#highligher").click(function () {
var e = jQuery.Event('click');
e.pageX = 250; //add a made up x/y coordinate to the click event
e.pageY = 250;
$('#plot canvas:first').trigger(e); //trigger the click event on the canvas
});
Here it is in action: http://jsfiddle.net/ryleyb/mHJm5/
The problem is you have to know where the slice you want to highlight is already. This would be easy enough to set if the graph is static. If it's a dynamic graph, you'd have to dig into the source of the pie code to figure out how to calculate where the pie slice is. It might be easier in that case to just have a copy of all the pie functions and manually draw on the pie overlay.
Just got this working by altering a few things...
I changed highlight and unhighlight in jquery.flot.pie.js to pieHighlight and pieUnhighlight.
Then, after these two lines in jquery.flot.pie.js...
plot.hooks.processOptions.push(function(plot, options) {
if (options.series.pie.show) {
I added...
plot.highlight = pieHighlight;
plot.unhighlight = pieUnhighlight;
We're maintaining selection state outside of the chart (as a backbone model). When a selection event (click) occurs, we set the selected slice in the model. When selection changes, we refresh the chart using a selection color for the pie slices that are selected.
var data = [];
var color = slice.index == selected ? '#FF0000' : '#0000FF';
data.push({label:slice.Label,data:slice.Value,color:color});
The snippet above uses blue for all non-selected slices, red for the selected slice. Your color logic will be more sophisticated.
NOTE: You can also use rgba CSS for the colors, which gives a really nice effect. For example:
var color = slice.index == selected ? 'rgba(0,0,255,1)' : 'rgba(0,0,255,0.5)';
