Heaven/TQA Posted July 4, 2008 Author Share Posted July 4, 2008 of course you should, James... Dis6502 is small but cool little tool... I missed it for years (who needs disassemblers anyway...) but this is an inteligent one... i only miss page up/page down support in the windows...

I looked at the file you had posted and thought it must be an Atari program at first. Quote Link to comment Share on other sites More sharing options...

Heaven/TQA Posted July 20, 2008 Author Share Posted July 20, 2008 (edited) well... I still use the Gremlin gfx for testing the sprite routines... you can move him around with joystick... but he stops near the wall...press console keys (start) to see the background buffer and you see why he is stopping. So I guess that I have to draw the action chars behind the walls as there have to be the door chars as well... sprite7d.zip Edited July 20, 2008 by Heaven/TQA Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted July 22, 2008 Author Share Posted July 22, 2008 ok. small update. you can move around and walk through doors. right now the Beyond-"walk through the floor map"-subroutines are not implemented but right now when walking through any day you walk to the next room (room_no++). and no...it is not written in basic even if you can see how the screen is build up. but it works. optimising comes at the end... it's cool... so next will be to get the nasties in. I am trying to convert one of the Beyond The Evil demo-sprites into the new format with Paint Shop Pro. Good lesson to have a look how the gfx guys have to prepare the gfx for the game. sprite8a.zip Quote Link to comment Share on other sites More sharing options...

Heaven/TQA Posted July 22, 2008 Author Share Posted July 22, 2008 Philsan... you seem one of the die-hard fans... hey...it's one simple sprite running around... so let us see what happen as more is happening on screen... Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted July 22, 2008 Author Share Posted July 22, 2008 (edited) ok. just tried to copy and convert some of Espire8's sprites. but what I am doing wrong? anybody an idea why the Gremlin is moving in y-direction smooth and my snake not? did I make something wrong in the gfx? just printed the gremlins sprite data for vertical movement in a screenshot... strange... the sprite seems not to move vertical 4 pixels or 8 pixels only 2? strange... but the artist did a good job as it fits perfect to the engine... ts...Heaven, Heaven... you should know your sprite engine...of course the vertical movement is done by the engine and not by preshifting sprite data in vertical. the Gremlin data is a plain animation... archive updated with the "fixed" snake. of course for a 8x16 sprite you can put for vertical movement the sprite into the "middle" of the 12x pixel size so the "jumps" are minimised. and sprite8c is for philsan only... sprite8b.zip sprite8c.zip Edited July 22, 2008 by Heaven/TQA Quote Link to comment Share on other sites More sharing options...
+Philsan Posted July 22, 2008 Share Posted July 22, 2008 Thank you very much. Having seen your hard work in the last months (years), having seen the beautiful artwork done by various artists, I am sure your game will be wonderful. Moreover, I think that your engine could be used to make other games. Perhaps not Robotron, but if it will be fast enough not only RPG could be done.

Heaven/TQA Posted July 22, 2008 Author Share Posted July 22, 2008 I am little tired after 4 hours of hard thinking and coding... I am little bit suprised that the 6 snakes as dummy nasties are moving so smooth while not slowing down the player but well... who cares. the slowdown will come when I will port over the game engine elements the next days like combat engine which needs to be adapted now to the higher resolution.

FastRobPlus Posted July 23, 2008 Share Posted July 23, 2008 btw. Kaz did the "evil" title screen I have as avatar... It might be covered elsewhere in this 21 page thread, but why did the name change from the uber cool Beyond Evil to the akward brokenEnglish sounding Beyond the Evil?

Rybags Posted July 23, 2008 Share Posted July 23, 2008 Agreed - "Beyond the Evil" sounds cheap and tacky. Quote Link to comment Share on other sites More sharing options...

Heaven/TQA Posted July 23, 2008 Author Share Posted July 23, 2008 I know... Kaz did a small mistake when we discussed the title screen but we haven't changed yet the screen to the "official" name Beyond Evil... but will be corrected sooner or later I guess. But thanks for pointing that out. Quote Link to comment Share on other sites More sharing options...
Rybags Posted July 23, 2008 Share Posted July 23, 2008 The title screen would also look better if his eyes rolled through 360 degrees. Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted July 23, 2008 Author Share Posted July 23, 2008 Kaz & I have some nice ideas regarding the title screen. So we have to wait. I guess he will work again on the title screen when I finished the port to the new engine. Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted July 23, 2008 Author Share Posted July 23, 2008 there are still some issues with the monster setting. have a look on the screens and the atr... press START to show the backbuffer at anytime... sometimes there are backbuffers set by the setsprite engine but no gfx data appears on the screen. I have no clue why. only reason could be that the sprite data is put there twice (EORing to 0) but this should be avoided as there is a check if there is already backbuff data there... ps. does LSR need a CLC? I guess no...or? sprite8a.zip Quote Link to comment Share on other sites More sharing options...
Rybags Posted July 23, 2008 Share Posted July 23, 2008 LSR is the same as doing a ROR with CLC beforehand (except the speed of course). Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted July 23, 2008 Author Share Posted July 23, 2008 (edited) sometimes there are simply logical errors...f.e. in the backbuffer each sprite id is drew over the occupied space... but what happens when ID #0 ? yes...it draws zero into the backbuffer which means empty space... grrrr... so... id counts from #1 to max monster... and now I do this "nice" trick... all tables relating to the monster id# are adressed like sta mxtab-1,x btw... similar "workrounds" you can find in commercial games as well...

Heaven/TQA Posted July 24, 2008 Author Share Posted July 24, 2008 ok. some bugs in the sprite engine ironed out... i guess this speed is fast enough imho for the game. what do you think? (hmm.... 8 sprites... good for the later ports...) sprite8a.zip Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted July 27, 2008 Author Share Posted July 27, 2008 (edited) so... next step is (again) the thing with the collision detection. How is the best thing to do? I want it to have it like in Zelda f.e. so you when pressing up and fire (attack) I want to attack N, if pressed SW then SW. so I have 16 areas to attack. now I have different ways to go. In the existing engine I am checking against the active monster: check_overlapping: lda monsterx sec sbc playerx bpl got_abs eor #$ff adc #1 got_abs cmp #3 bcs no_overlap;bcs lda monstery sec sbc playery bpl got_abs2 eor #$ff adc #1 got_abs2 cmp #3 bcs no_overlap;bcs ; jmp end_game lda #0 rts no_overlap lda #255;returns -1 when overlapp rts so... but assume that at top of the player there could be 3 monsters (NW,N,NE) so I thought I use the "check background" function to see what monster is there... but f.e. at NE direction there could be several monster occupying the space as the monsters are moving in pixel steps and not in char steps... so my function would return the monster IDs ored together... but I guess this would not make sense... too many different things to consider... so...how would a Zelda like game would do it? checking the "sprite collision" of the sword against the enemies? or the "overlapp" kind of approach? anybody any experience what would be a fast and convinient way? my function should simply return the ID of the monster which the player would probably hit. the engine then would call the "attack against monster" procedure with all the probability checks and damage calcs...

Rybags Posted July 27, 2008 Share Posted July 27, 2008 I don't get it. Aren't you using the backbuffer as prevention for objects occupying the same space? That aside - you obviously at some stage will have the X,Y origin of the monsters available if you're plotting them in character mode, so store those in an array. Then you can check the sword for overlap. You probably want a subsequent step that does fine checking in case of overlap as obviously e.g. a monster occupies only pixels 0,1 vertically then potentially the sword could overlap that character but only in the lower pixels. Possibly calculate the degree of damage as being dependant on the amount of overlap between the sword and each enemy it coincides with.
