Hello everyone and thanks in advance for any help given here.
Basically i added to the: Texture2D.ReadPixels
What i am trying to do is save the cameras view to a RawImage UI component and allow it to be saved on that RawImage so that when i load the games playerprefs, that image is still there and they can choose what save they want to load. A similar reference is the way skyrim presents saves in the form of images of the scene view.
Here is what i have working:
-Load & Save system
-Setting the RawImage to the scene view
Here is whats not working:
-Playing the scene again in the editor a second time removes the Texture from the RawImage
Here is my script:
using UnityEngine;
using UnityEngine.UI;
using System.Collections;
using System.Collections.Generic;
using plyBloxKit;
// Here we make sure you added the required components to this camera,
// if not, we will add them for you when you attach the script.
// WARNING: Be sure to place this on a camera.
[RequireComponent (typeof (Camera))]
[RequireComponent (typeof (plyBlox))]
public class ScreenGrab : MonoBehaviour {
// This variable will present our bool that will be called when the
// player saves the game so that we can grab a camera snapshot and
// run our events.
public bool setImage = true;
// This variable holds the object with the blox component on it
// and will fire a custom state when the player saves the game.
public plyBlox bloxLogic;
// This variable is the number that will be set on the script so that it can decide
// which slot image to save to. The values by default range from 1-3 with 0 being null.
public static int saveSlotNumber = 0;
// OPTIONAL: Uncomment the variable line below if you want to be able to see the slot number change
// while inside the inspector. Be sure to comment the above variable out if you want this one active.
//public int saveSlotNumber;
// These variables hold our save game slot images. Each one correlates
// to its respective slot to be called in our events below. To add more
// slots, simply copy and paste the whole variable line and change the
// variable name to a unique name like shown below.
public RawImage saveSlotOneImage;
public RawImage saveSlotTwoImage;
public RawImage saveSlotThreeImage;
// OPTIONAL: These variables will serve as optional offsets that you can apply to
// the screen capture ranging from any value in the X or Y axis.
public float imagePosXOffset = 0;
public float imagePosYOffset = 0;
// These variables will capture the cameras view in accordance to the end users actual screen width
// and size.
private int grabWidthResolution = Screen.width;
private int grabHeightResolution = Screen.height;
// This function will be called from the camera after regular rendering is done.
void OnPostRender() {
// Here we will first check if our bool is True, if so, capture the scene view and save it to a texture
// in accordance to the variables we have set in the inspector, excluding the getResolution variables.
if (setImage) {
Texture2D tex = new Texture2D(grabWidthResolution, grabHeightResolution);
tex.ReadPixels(new Rect(imagePosXOffset, imagePosYOffset, grabWidthResolution, grabHeightResolution), 0, 0);
tex.Apply();
// Here check if the slot we want to save to is the correct slot and if so,
// we will set our save slot image to our newly captured screen view.
if (saveSlotNumber == 1) {
saveSlotOneImage.texture = (Texture)tex;
Debug.Log("Save Slot One Was Set");
}
// Here check if the slot we want to save to is the correct slot and if so,
// we will set our save slot image to our newly captured screen view.
if (saveSlotNumber == 2) {
saveSlotTwoImage.texture = (Texture)tex;
Debug.Log("Save Slot Two Was Set");
}
// Here check if the slot we want to save to is the correct slot and if so,
// we will set our save slot image to our newly captured screen view.
if (saveSlotNumber == 3) {
saveSlotThreeImage.texture = (Texture)tex;
Debug.Log("Save Slot Three Was Set");
}
// Here we will call an event from the plyBlox gameobject we specified in
// the inspector. To change the events name that will be called, edit the
// string after "blox.RunEvent".
plyBlox blox = bloxLogic.GetComponent<plyBlox>();
blox.RunEvent ("Test");
// Here we finish our screen capture logic and turn the fuction off so that
// it can be called again.
setImage = false;
}
}
}
