brief introduction

MiniMap It can help us quickly realize the function of small map , The tool has been uploaded to my development framework SKFramework Medium Package Manager In the development kit manager , As shown in the figure , Click on the bottom right corner Install Button to download and install .

Realization principle

1. Take... In the scene z The positive direction of the axis is up 、 With x The positive direction of the axis is right ;

2. Take the lower left corner and the upper right corner of the scene as two benchmarks , Record as leftBottom、rightTop;

3. Put the... Of the target object in the scene Transform Record as target3d;

4. Will represent the target object in the interface Icon Icon's RectTransform Record as target2d;

5. Put the small map RectTransform Component record is mapRt;

6. Divide the length of the mini map by the length of the scene to get the proportion in the horizontal direction ;

(mapRt.rect.width / (rightTop.position.x - leftBottom.position.x))

7. Divide the width of the mini map by the width of the scene to get the proportion in the vertical direction ;

(mapRt.rect.height / (rightTop.position.z - leftBottom.position.z))

8. Calculate the length and width of the three-dimensional target object from the base point of the lower left corner , Record as horizontal、vertical;

(horizontal = target3d.position.x - leftBottom.position.x)

(vertical = target3d.position.z - leftBottom.position.z)

9. Calculate in the small map Icon The length and width of the icon from the lower left corner , Record as x、y;

(x = horizontal * Proportion in horizontal direction )

(y = vertical * Scale in the vertical direction )

10.Icon Icon sets the anchor to the lower left corner , Set its position .

(target2d.anchoredPosition = new Vector(x, y))

Instructions

isEnableRot：Icon Whether the icon rotates with the rotation of the 3D target

isEnableRotLerp： Whether to use interpolation operation when calculating rotation value

rotationLerpTime： The time required to interpolate to the target angle
