You are using...
PHP Code:
new GuiButtonCtrl("MyGUI_Button1") {
text = "Warp";
width = 80;
x = 215;
y = 143;
normalbitmap = "guiera_tab.png";
mouseoverbitmap = "guiera_tab.png";
pressedbitmap = "guiera_tab.png";
}
... and normal/mouseover/pressedbitmap are only for
GuiBitmapButtonCtrl's. Instead, do this:
PHP Code:
new GuiButtonCtrl("MyGUI_Button1") {
useOwnProfile = true;
profile.bitmap = "guiera_tab.png";
text = "Warp";
width = 80;
x = 215;
y = 143;
}
