easmith Posted January 23, 2020 Author Share Posted January 23, 2020 (edited) Sorry for so many updates.... but been on a roll. This is pretty much complete now except for some cosmetic tweaks here and there . Probably will stop working unless I hear any feedback. I have 2 Player mode active now, and have shored up the in/out detection a bit more. I would really appreciate if anyone catches any bugs . I am pretty happy with the gameplay. I think it looks good in Stella but am not crazy about the flicker on CRT . So not sure if a cart will be made yet. A cart for Beer Pong and 1 vs 1 Baseball are in the works . But I hope someone can enjoy it ! I am a pretty avid tennis player and have tried to make the game play fairly realistic .

easmith Posted January 23, 2020 Author Share Posted January 23, 2020 (edited) I finally won a match against the AI !! 6-5 4-6 6-5 Very tough and I have played a lot. I have adjusted the AI so that it is easier to win a game when you are bottom player ( slowed down the top AI just a bit) . A strategy also when you are bottom player that works well is to approach the net. So instead of having an advantage when serving , you have a slight advantage when you are top player. So winning a game as bottom player is kind of like breaking a serve, in that it is hard to accomplish. I also just realized after playing a bunch that pants color did not change when the players changed sides! fixed that . Still an occasional bad call ( maybe once per match) , but that happens in real life too ! Edited January 25, 2020 by easmith 1 Quote Link to comment Share on other sites More sharing options...

Stil some fine tuning needed both graphically and gameplay -wise . For example , while the AI player when at top is just about right , the AI player when at bottom is currently too slow/ dumb . I am able to get shots by it too easily . I finally found a bug with the AI movement that I have fixed that has helped with that , but still need to play more to get the right speed for the bottom AI player . Getting close . I am trying to wait until I get it closer to post another update . 1 Quote Link to comment Share on other sites More sharing options...

devwebcl Posted January 26, 2020 Share Posted January 26, 2020 The game is very fast, it requires a while to start beating the cpu. It would be good to have a novice/beginner level, much slower. This way the rally could be longer. Quote Link to comment Share on other sites More sharing options...

It would be good to have a novice/beginner level, much slower. This way the rally could be longer. Thanks for the feedback . I will work on it . Here is my current plan : novice mode where you get 2 fast shot / winner attempts per rally . So you have to pick your spots . Expert mode with unlimited fast shots . I also slowed down the fast shot just a little I researched that 70 % of pro rallies last 4 shots or fewer . So wanted to make it fast on purpose . Also, you have to do a little bit of guessing where the ball might go in order to have a chance at some shots, which to me adds a additional element . But I think both options are a good idea and will add them . Edited January 28, 2020 by easmith 2 Quote Link to comment Share on other sites More sharing options...
easmith Posted January 28, 2020 Author Share Posted January 28, 2020 (edited) Update: I did not like the 2 fast shots per rally option after playing for a bit. Hard to keep track. I have changed it to : Unlimited fast shots, but only off bounce-- cannot hit fast winner if ball is in air. This is a bit more realistic. Also tweaked colors a bit corrected a few minor graphics issues Edited January 30, 2020 by easmith 2 Quote Link to comment Share on other sites More sharing options...

easmith Posted January 30, 2020 Author Share Posted January 30, 2020 (edited) After playing / testing a lot, I am pretty happy with this version. Rallies are longer , but can still hit the occasional winner . I think the AI opponent is tough but beatable . I think that the ability to hit 3 different types of shots ( normal, fast , and lob) and the ability to control the shot placement with joystick, makes this different enough from the previous 2600 tennis titles. Note :I was finding that when trying to do lob shot ( up or down on joystick depending on whether at top or bottom ) , I would move the player out of the way of the ball and miss the shot. So now, if button is pressed the player cannot move straight up (if top player) or straight down ( if bottom player). So press button when attempting a lob shot and it is easier . ( Normally the button makes fast shot , but not when pressing in direction for lob shot). 1 vs 1 Pro Tennis readme.pdf Edited February 2, 2020 by easmith fixed a graphical bug in bottom swing.

easmith Posted January 31, 2020 Author Share Posted January 31, 2020 Final update in previous post . Fixed the last bugs I am aware of after playing for quite a bit .

devwebcl Posted February 1, 2020 Share Posted February 1, 2020 Now it is much better tennis game. ✌️ I wonder about AI, if it is implemented to play as baseliner? Playing the default level, I get only volleys, although, this is not wrong (very playable), still I miss some baseline shots. Quote Link to comment Share on other sites More sharing options...

If you push up , up left, or up right during ( or just after ) shot when you are bottom player, notice how the AI retreats to baseline. Then he will shoot baseline fast shots off the bounce ( sometimes) . If you are top player , pushing down ,down left , or down right will accomplish same . Sometimes the AI will even go to baseline even if you hit short shot. To hit fast winners, has to be off bounce by pressing button during shot. Try this and tell me if it makes it better Edited February 1, 2020 by easmith 1 Quote Link to comment Share on other sites More sharing options...

devwebcl Posted February 5, 2020 Share Posted February 5, 2020 I finished (and lost) a complete game. This is my feedback: bugs? - when CPU won, then the word "in" appears, and a sound/pitch kept permanently (it looks like a bug) - when serving from the bottom, always hit outside of the correct service-box (fail service). new features: - It would be nice that AI fails some service/serve some time. - Also, the player could miss some service (if he/she moves the joystick for a longer time to right or left). - I miss a parallel service (AI & player) - player & CPU could move before serving, this way we can get different angles. - With the above features, we could do aces. - Is it possible to implement the messages "match point", "set point"? (when corresponding). Quote Link to comment Share on other sites More sharing options...

Good suggestion. I will see what I can do about varying the service position and angle . I don't know about aces since the speed is not that fast for serves. 2 hours ago, devwebcl said: - Is it possible to implement the messages "match point", "set point"? (when corresponding).

Folks will just have to look at the situation and figure it out. For one, I only have 3 bytes of ram remaining . I might be able to add "SET PT" , but just determining set point will require a routine that looks at game totals for both players and current game score for both players . If I am not burned out after other issues are addressed I might see about it .... 1 Quote Link to comment Share on other sites More sharing options...

In this update I have added variation to serves. For now it is random, but will eventually add the ability to select placement with stick. Even with the random selection it adds variety and you get the occasional ace. Will need to impose some risk in choosing a serve that is in corner or down the center line. So this will require adding some percentage of these serves that land out and then judging faults , then going to second serve or double fault. Doable though . 1vs1ProTennis2-7-20.bin Edited February 7, 2020 by easmith 3 Quote Link to comment Share on other sites More sharing options...
