Socoder -> Blitz -> Fancy-pants graphics in Blitz

Phoenix	While sitting down this morning, sipping on a lovely cup of tea, I was suddenly struck by that strange notion of making a tiny little game in Blitz. Then I remembered how I was always so angry that it was so limited, graphically. Then I remembered how I tried to make an extension library to correct all of that last year and then failed. Then I tried to overlook that fact and got to work. After a couple of hours of hacking, there is some light at the end of the tunnel: download example (510k). Here's the code used: Include "BlitzExKeys.bb" ExGraphics(800, 600, 0, 2) img = ExLoadImage("godzilla.png") Type Thing Field r, g, b, a Field x#, y#, ang# Field spd# End Type For i = 0 To 500 t.Thing = New Thing t\x = Rand(0, 800) t\y = Rand(0, 600) t\r = Rand(0, 255) t\g = Rand(0, 255) t\b = Rand(0, 255) t\a = Rand(0, 255) t\ang = Rand(0, 360) t\spd# = Rnd(1, 2) Next ExClearColor(255, 255, 255) While(Not ExKeyHit(EXK_ESCAPE)) ExBeginDraw For t.Thing = Each Thing t\x = t\x + Cos(t\ang) * t\spd# t\y = t\y + Sin(t\ang) * t\spd# t\ang = t\ang + .1 If((t\x < -64) Or (t\y < -64)) Then t\spd = -t\spd If(t\x > 800-64) Then t\spd = -t\spd : t\x = t\x - 5 If(t\y > 600-64) Then t\spd = -t\spd : t\y = t\y - 5 ExRotation(t\ang) ExAlpha(t\a) ExColor(t\r, t\g, t\b) ExDrawImage(img, t\x, t\y, 0) Next ExEndDraw Wend End --v As you can see, it's not exactly like vanilla Blitz, but it's close enough. There are many rough edges though, and it's far from complete. This can be changed, given that: Does the example even work? Provided that it does, is the speed acceptable? Is anyone interested in this, apart from me? I might try to enter the next WW using this, in any case.

Jayenkai	Celeron says no, but... With an obvious reason I'd be interested if it's actually quicker than Blitz3D+2D things, but.. Well, if you remember my SoC tests, I kinda gave up when I realised that I wouldn't be getting multitudes of tilemaps onscreen all at once.. In many ways, B2D isn't fantastic, but you can at least draw tiles quick.. so.. you know.. there's that -=-=- ''Load, Next List!''

JL235	I get the same error.

Scherererer	Same error

Jayenkai	Works on both systems, once you add the specific DLL! There's probably a way to be less specific with your DLL request. .. Or, you know, MS could STOP GOD DAMN BREAKING EVERYTHING!! -=-=- ''Load, Next List!''

Phoenix	I used the DirectX utility library, so that's why it requires an extra DLL. Add the file in Jay's post and it should hopefully work. I can probably remove all of the utility stuff (since it's mostly a convenience), so that the extra file isn't needed. Since you got it working Jay, did it run decently? I'll work a bit more on it and then add a frame rate somewhere, then people can say how it performs. \|edit\| By the way, a 20x15 tile map runs perfectly over here, even with rotations and alpha blending. \|edit\|

Jayenkai	Um, I think it ran decently Seemed about the same speed on both the crappy-celeron, and the decent Quadcore. -=-=- ''Load, Next List!''

CodersRule	I didn't get that error that everyone else got, but I got "user lib not found" error generated by blitz.

JL235	Works for me now.

Evil Roy Ferguso	Runs smoothly on a 1.8GHz Celeron with 2GB RAM and integrated Intel graphics. I'd test it on my 2.0GHz Core 2 Duo + 2GB RAM and NVidia something notebook too, but I'm not honestly sure if that's necessary, all things considered.
