H! I know how to get the x and y with blitz 3D but how must I do this with blitzmax ? strict Local button:TImage = LoadImage("incbin::images/button.jpg") While Not KeyHit(KEY_ESCAPE) Cls ResetCollisions DrawImage button,200,34 drawtext button.X() and button.Y(),0,0 Flip Wend --- output 200,34 |

... how do you get the imagex/y in B3D? Do you mean the image's x/y handle? That case you can either use :local x:float,y:float gethandle(x,y) print x + " " + y to get the 'universal' handle or print image.handle_x + " " + image.handle_y to get a specific images handle. This is using the Image method rather than a function which I can't seem to find. <EDIT> p.s. or if you really mean xpos,ypos use FlameDuck's suggestion. |

TImages do not have coordinates. If you wish to do this, you should create your own type (for instance Button) and give that X:Int, Y:Int and button:TImage fields. The advantage to this is that the same image can be at more than one position at a time. |

@tonyg must I like it like this ? strict Local button:TImage = LoadImage("incbin::images/button.jpg") local x:float,y:float gethandle(x,y) While Not KeyHit(KEY_ESCAPE) Cls ResetCollisions DrawImage button,200,34 print button.handle_x + " " + button.handle_y drawtext button.X() and button.Y(),0,0 Flip Wend ------------- @ FlameDuck I'm going to make some type's later. But this was only my "starting with blitzmax" code |

Like this? Your code had a few errors and, I hope, you understand that in this case button.handle_x/y will be returning 0. The 'handle' is the drawpoint for the image (like a hotspot).For completeness sake : If you're new to Bmax I strongly recommend you follow Beginner's Guide to Bmax , Learning 2D Game Programming With BlitzMax and Learning Object-Oriented Programming in Blitzmax . There are a few other use tutorials as well. |
