(and also i use ngui free) using UnityEngine; using System.Collections; public class INGAme : MonoBehaviour { //GUI public bool buildPanelOpen =false; public TweenPosition BuildPanelTweener; public TweenRotation BuildPanelArrowTweener; //Placement public Transform placementPlanesRoot; public Material hoverMat; public LayerMask placementLayrerMask; private Material originalMat; public GameObject lastHitObj; // build public Color onColor; public Color offColor; public GameObject[] allStructures; public UISlicedSprite[] buildBtnGraphics; private int structureIndex = 0; void Start() { structureIndex = 0; ApdateGUI(); } void ToggleBuildPanel() { if(buildPanelOpen) { //ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); RaycastHit hit; if(Physics.Raycast(ray, hit, 1000, placementLayerMask)); { if(lastHitObj) { lastHitObj.renderer.material = originalMat; } lastHitObj = hit.collider.gameObject; originalMat = lastHitObj.renderer.material; lastHitObj.renderer.material = hoverMat; } BuildPanelTweener.Play(false); BuildPanelArrowTweener.Play(false); buildPanelOpen = false; } else { if(lastHitObj); { lastHitObj.renderer.material = originalMat; lastHitObj = null; } BuildPanelTweener.Play(true); BuildPanelArrowTweener.Play(true); buildPanelOpen = true; } if(Input.GetMouseButtonDown(0) && lastHitObj) { if(lastHitObj.tag == "PlacementPlane_Open") { GameObject newStructure = instantiane(allStructures[structureIndex], lasHitObj.transform.position, Quaternion.identity); newStructure.transform.localEulerAngles.y = ( Random.Range ( 0, 360 ) ); lastHitObj.tag = "PlacementPlane_Taken"; } } } void UpdateGUI () { //Go through all structure buttons (buttons in the build panel). and set them to “off” for(UISlicedSprite theBtnGraphic )//in buildBtnGraphics { theBtnGraphic.color = offColor; } //set the selected build button to “on” buildBtnGraphics[structureIndex].color = onColor; } void SetBuildChoice ( GameObject btnObj ) { string btnName = btnObj.name; if ( btnName == "Btn_Canoon") { structureIndex = 0; } else if ( btnName == "Btn_Missle" ) { structureIndex = 1; } UpdateGUI (); } }
