| Hey friends, Im a new to this code and am not sure if I am doing this right. I'm also not sure if I am drawing a new picture each and every time I move. Does this look right? Thanks ps. does anyone know if the "Learn how to program with Blitz 2D" is any good? Graphics 640,480 SetBuffer BackBuffer() Global player=LoadImage("graphics\alien.bmp") Global speed=3 Global p.player=New player Type player Field x,y End Type While Not KeyHit(1) updateplayer() drawplayer() Wend FreeImage player End Function updateplayer() If KeyDown(203) Then p\x=p\x - speed If KeyDown(205) Then p\x=p\x + speed If KeyDown(200) Then p\y=p\y - speed If KeyDown(208) Then p\y=p\y + speed If p\x<-25 Then p\x=650 If p\y<-25 Then p\y=490 If p\x>650 Then p\x=-25 If p\y>490 Then p\y=-25 End Function Function drawplayer() Cls DrawImage player,p\x,p\y Flip End Function |

| Looks fine to me I never declare types as globals, appears to be no need. Although if u didnt u would be calling them. I tend to use globals when I have to, otherwise local variables, can help with debugging on larger projects imo. No idea on the book, I ask questions here when I have any. |
