Picks the entity positioned at the specified viewport coordinates. Returns the entity picked, or 0 if none there. An entity must have its dxEntityPickMode set to a non-0 value value to be 'pickable'. See also: dxEntityPick, dxLinePick, dxCameraPick, dxEntityPickMode. |

Use pick_geometry mode no.2 for polygon collision. ground_tex=dxLoadTexture("media/Chorme-2.bmp") dxEntityTexture plane,ground_tex cube=dxCreateCube() dxEntityPickMode cube,2 ; Make the cube entity 'pickable'.
