Examples of org.mt4j.components.MTCanvas

org.mt4j.components.MTCanvas
MTCanvas is the root node of the component hierarchy of a MT4j scene. To make a mt4j component visible and interactable you have to add it to the scene's canvas or to a component which is already attached to the canvas. The canvas then recursivly updates and draws all attached components each frame. @author Christopher Ruff

    this.sceneCam.update();
    this.sceneCam.setZoomMinDistance(60);
    this.mainCanvas = new MTCanvas(mtApplication, name + " - Main Canvas", sceneCam);
    
//    preDrawActions = new LinkedList<IPreDrawAction>();
    preDrawActions = new ArrayDeque<IPreDrawAction>();
