    Default Moving an image around under a touch

    I am playing around with the TouchTestComponent to try better understand the entity/component framework. I am trying to get image/texture to show upon a touch, move around during the touch and then disappear. I am having limited success.

    Is there an example of this I am missing?

    Found this posting, but not able to apply this tidbit.

    I am adding an entity variable to the TouchObject and trying to create and destroy based upon the messagetype coming into the OnInput. So far still missing something.

    Well, there should be no problem doing bitmaps instead of filled squares. I can't really see what's wrong without code but...

    Keep in mind that if you add entities, they aren't going to draw unless they are A, added as a child to an entity that has draw focus, or B, you add draw focus to them.

    Another way would be to just init a Surface and blit it yourself instead of the rect here:

    void TouchTestComponent::DrawTouch(uint32 touchID, CL_Vec2f vPos)
    	DrawFilledSquare(vPos.x, vPos.y, 40, m_touch[touchID].m_color, true);
    	GetBaseApp()->GetFont(FONT_SMALL)->Draw(vPos.x-5, vPos.y-20, toString(touchID), MAKE_RGBA(0,0,0,255)); //<-- change this to something else

    Default Like this?

    void TouchTestComponent:rawTouch(uint32 touchID, CL_Vec2f vPos)
    Surface *pSurf = new Surface();

    This seems to get me what I need. I was trying to this:

    Entity *pBG = CreateOverlayEntity(GetParent(), "MyEnt", "", vPos.x,vPos.y);

    which left a trail of images all over the place.

    Default Even better ...?

    void TouchTestComponent::DrawTouch(uint32 touchID, CL_Vec2f vPos)
    SurfaceAnim *pSurfAnim = GetResourceManager()->GetSurfaceAnim("interface/Cobbles_grey_VL.rttex");
