问题 I'd like to get a single sprite which GameObject has in a SpriteRenderer component. Unfortunately, this code returns the whole atlas, but I need to a part of this atlas. Texture2D thumbnail = GetComponent<SpriteRenderer>().sprite.texture; 回答1: There is no native API to get single sprite from the SpriteRenderer and no API to access individual Sprite by name. You can vote for this feature here. You can make your own API to get single sprite from Atlas located in the Resources folder like the

问题 I'm trying to use a sprite image for google map marker but it does not display. Here is the code I'm using function setMarkers(map, markers) { var google_image = new google.maps.MarkerImage("http://www.mydomain.com/images/bodycss/pointer.png", new google.maps.Size(32, 32), new google.maps.Point(28, 32)); for (var i = 0; i < markers.length; i++) { var sites = markers[i]; var siteLatLng = new google.maps.LatLng(sites[1], sites[2]); var marker = new google.maps.Marker({ position: siteLatLng, map

问题 I have a sprite : ombreoeuf1 = [CCSprite spriteWithFile:@"mangeurcentremieu3_03.png" ]; ombreoeuf1.position = ccp(240,160); [self addChild:ombreoeuf1]; And I would like to rotate it constantly around an anchor point. How can I do it? 回答1: You can first set anchor point by setting the property anchorPoint , for example: [ombreoeuf1 setAnchorPoint:ccp(0,0)] and then set rotation (in degrees) by setting another property rotation : [ombreoeuf1 setRotation:90] anchorPoint and rotation are both

问题 I am rotating a clock hand around clock center, and I am using: Vector3 dir = mouseClickPos - transform.position; float angle = Mathf.Atan2(dir.y,dir.x) * Mathf.Rad2Deg; transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward); And it is working like a charm. But I need it not to go smooth but to skip around 15 degrees. How can I do that? 回答1: Try angle=Mathf.Round(angle/15f)*15f (sorry for the wrong math at first, need coffee) 来源： https://stackoverflow.com/questions/24673043/rotate

Thanks in advance 回答1: It is important to distinguish the difference between Colliders and Triggers. Colliders are used

问题 I am beginning to write a game in LibGDX, only just beginning. I have got a basic tile map loaded, a player sprite and can move the character around and the screen (camera) scrolls around - perfect. I have two overlayed textures in the bottom right of the screen, a left and right arrow, which are used as the joypad to control the character. I position these in relation to the players.x position, which is always fixed to the centre of the screen. Cool so far .... As below: ////////////////////

问题 I want to know , if you can , join two sprites in libgdx . Let me explain, I have a spaceship that I have to turn in my game ... and is the first sprite . another sprite I would put on the tip of the spacecraft so that when it turns me I through the second sprite I can always know the coordinates and so derive a vector in order to advance my ship . I'm new to libgdx and if anyone had any idea would be grateful. Thank You. EDIT : I would follow that always render the position of the other

问题 I currently have a custom shader draw a gradient on a skydome and would like to have a sun/moon in front of the skydome (from users perspective). The easiest way to do this is to have sprites for the sun and moon but the problem that arises is that the sprites get lodged within the skydome (sprite is partway in front and partway in back of the skydome). I have attempted to solve this with polygonoffset, but that doesn't seem to work on sprite objects. So my question is, how can I setup a sun
