Swap GUI Texture with button press in C#

Question

alt text

So essentially, what I want to do is highlight the button I press. I have got a way to do it but the problem is that my frame rate goes from 300 to 10 whenever I press a button. Here is what I did, but is there a better way to do it? I couldn't figure out how to just swap textures so this is the long way:

    if (playerScript.GPress == true)
    {
        GUI.DrawTexture(GPressImage);
    }
    if (playerScript.HPress == true)
    {
        GUI.DrawTexture(HPressImage);
    }
    if (playerScript.VPress == true)
    {
        GUI.DrawTexture(VPressImage);
    }
    if (playerScript.BPress == true)
    {
        GUI.DrawTexture(BPressImage);
    }
    if (playerScript.NPress == true)
    {
        GUI.DrawTexture(nNPressImage);
    }
    if (playerScript.NoPress == true)
    {
        GUI.DrawTexture(NoPressImage);
    }

This does work. Its just not efficient in the least.

SOLVED: Essentially this is the change I made:

if (KeyCode.G) { Resources.Load("GPress"); }

 else if (KeyCode.H)
 {
     Resources.Load("HPress");
 }

 else if (KeyCode.V)
 {
     Resources.Load("VPress");
 }

 else if (KeyCode.B)
 {
     Resources.Load("BPress");
 }

 else if (KeyCode.N)
 {
     Resources.Load("NPress");
 }

 else if (KeyCode.G || KeyCode.H || KeyCode.V || KeyCode.B
     || KeyCode.N)
 {
     Resources.Load("NoPress");
 }

you can have variables with the different images of your buttons, pressed and unpressed, this will give you like 7 images 5 of 'g-h-v-b-n' unpressed, and 2 of 'g-h' pressed you only have the GUI.DrawTexture() once, but having a texture that will change its image value, once the button is pressed

GUITexture  myDisplayedImage;
void Update()
{
    if(playerScript.GPress)
        myDisplayedImage = GpressedImage;
    //this you can change the material or the texture, your choice
}
void OnGUI()
{
    GUI.DrawTexture(myDisplayedImage);
}

this is the main idea of what i would do, also instead of drawing on the OnGUI, i would change that for a plane object, with the plane you will need change the material, as i know is more efficient than OnGUI, but first make the try

hope this helps you

Ah, thats close to what I was doing. I was wondering if I could search through the project to find a texture and assign it to one variable so that I don't have to allocate 7 images. And even then, would that fix the 300 to 10 frames issue?

Ahh I missed that last part. Thanks, I'll give it a shot.

actually ins$$anonymous$$d of the assigment it could be a Resources.Load("myimage") as Texture or something, i think the frame rate problem should not be there anymore, if dont work with that, try the planes thing
