Remove the mSpriteImageCount property that was created by the previous step.Ģ6. Convert SpriteImageCount into a computed property.Ģ5.

Add the following code to the Surface.Resized event handler:ĩ. X3_EnableLight OpenGL.GL_LIGHT0, new X3Core.X3Light(0, 1, 1)Ĩ. Add the following code to the Surface.Open event handler: Add the following code to the SurfaceWindow.Paint event handler:ħ. Position and size Surface to fill the window, and set its locking to left, top, bottom and right.Ħ. We keep on doing this until we reach the last frame, at which point we can switch back to the first frame.ĥ. With a timer we then change the UV-map coordinates of the polygon to the coordinates of the second frame after a short delay, and redraw the polygon with the new coordinates. To animate a "sprite mapped" polygon we simply bind to the sprite sheet texture, and set the UV-map coordinates of the polygon to the coordinates defined for the first frame. To save memory we only store the top-left coordinate and bottom-right coordinate because the other two coordinates can be determined from these two. Once we have all the UV coordinates defined for the sprite sheet, we compile a list of UV coordinates for each frame and store these lists in an array. The UV Maps for the red, green and blue frames in the sprite sheet above are as follow: Once a polygon has been "sprite mapped", we can still apply the same rotation, translation and scaling operations to the polygon, like we would with any other polygon.Īn easy way to implement a sprite with OpenGL is to load the sprite sheet like you would load a normal texture, and then to define the different UV coordinates for the frames. The only difference between a texture and a sprite, is that a sprite is a texture whose image constantly changes. by applying the same technique we did with texture mapping. The final result of the animation sequence might looks as follow.īut how do we add 2D sprites to our 3D application, and still have access to all our 3D routines?. The sprite animation applies the following logic: The animation sequence might be illustrated as follow: The duration of the pause will depend on the effect you want to achieve with the sprite. Sprite sheet obtained from .Īn animation is created from a sprite sheet by showing one frame at a time with a short pause between each frame. Below is a sprite sheet that might be used to create an animation of a flying bird. With our exchange rates and limited budgets, this option becomes way to expensive.A sprite is an animation with its frames stored as a single bitmap, better known as a sprite sheet or a tile sheet. PS: Using third party plugins is a no-no for us.

#XOJO GET LIST OF PROPERTIES IN A MODULE SOFTWARE#

This new software forms the basis of a new business venture, and if it is not stable, its a no-go. Problem remains.Īny ideas would be helpful, otherwise this may just be the end of Xojo for me (that after many, many years all the way back from the early versions of Real Basic). I have also changed the Listboxes to using NoHeaders etc. Sometimes the app will run for hours, no problem, other times it terminates on startup or after a few seconds (tracing the error gives something with WinGUIF.dll - can’t remember it exactly now). I have spent the last week intensively hunting down the problem, changed all the connections from to URLConnections. Works absolutely brilliantly and reliably on Mac, problems to no end on Windows. In that way we have reduced network traffic by 95%. So the program was redeveloped using an API. The problem is that for this to work, the program needs a persistent database connection - here by us in Africa that is not an easy thing to achieve and establishing a reliable connection via the internet…

Originally I made use of the mysql engine and this worked absolutely fine - under both Mac and Windows. From what I have read here in the Forum, the problem seems to be arising in the URLConnection /. These cannot be replicated or repeated, the app simply shuts down.

On Mac the app runs flawlessly, in Windows I get random shutdowns on the software. I have a question regarding the deployment of a database intensive app on Windows 10.
