Checkout my new game - Invasion

[3dcgi]

Hi all. In the past few months a friend and I have been working a game. Please try it out and let me know what you think. Here is a link and description.

http://www.zmgames.com/

Invasion is a free 3D Action Puzzle game based on the classic arcade game, Rampart. The gameplay has elements of Missile Command and Tetris.

Some of the OpenGL rendering techniques used include stencil shadow volumes, animation with vertex programs, vertex arrays, and particle systems. A Quake style console lets certain variables be modified on the fly.

Thanks.

even works fine on Kyro

tho' my mouse goes completely doolally
Intellimouse Explorer V3.0
i have to zoom in with the cursor before i can position a cannon or piece of wall
cursor does not correspond with mouse position and cannon shoots downscreen constantly even though it's facing out to sea
mouse buttons are v.slow to respond and sometimes don't at all

[3dcgi]

Those are some strange results. Can you tell me your system specs? You've already said you have a Kyro, but what about your OS and processor?

Did you try closing the game and reloading it again just incase something wierd happened?

Also, please try turning off shadows and turning down the texture and geometry detail just to make sure the sluggish mouse isn't do to performance slow downs.

[deviantchild]

ok, scrap the unresponsive mouse bit - that must have been before i realised that i had to zoom in to get it to work

but your suggestion still didn't solve anything

the screen position of the mouse crosshair doesn't correlate with where the walls go - meaning, i reach the top of the screen with the mouse and the piece of wall i want to place only gets halfway up the screen
this also seems to be related to the cannon always firing downscreen - i can change the angle slightly by taking the crosshair to the four extremities of the screen

yes, there is a slight frame difference with low/high settings, but it still runs at a playable framerate on the highest

Thanks deviantchild. Your system has some specs I haven't tested with. This weekend I'll look through the code to see what I can find. And it shouldn't be necessary to zoom in either so that could be a related problem.

If anyone else has a similar problem please let me know.

[3dcgi]

deviantchild. I uploaded a new build that uses a different method to get the target locations from mouse clicks. If I'm hitting a bug in the Kyro drivers this might fix the problem. If it doesn't then I have no idea what the problem is and what's causing it.

If you don't mind testing this please do so. Thanks.

3dcgi,
SHITE! sorry for wasting your time
i haven't even tried your new version as i found the problem:-
i went to create a 3d Optimisation profile for the game running under OpenGL (as it does) and when the new profile apppeared it already had "Enable Internal Depth/Stencil buffer" and one of it's related settings "Enable Depth/Stencil Buffer Storing " [ZStore] checked - this was the problem
i don't know why, but it was inheriting these settings from the "Default" [global] OpenGL profile - if i uncheck them they just reappear
fttb i've resorted to using a "Custom" [global] profile so that other OGL games aren't potentially affected by this - ZStore is handy, but not on everything ;)
so it's sorted and running perfectly now
sorry again for the unnecessary work you put in on the new version

nice game btw - Ramparts always was a simple but great gaming concept

[3dcgi]

No problem deviantchild. The change I made wasn't very difficult, but its nice to know there wasn't a bug.

By the way, for anyone that tries the game let me know if you get a high score. My personal best is just shy of 1000 on hard. I've gotten higher than that on easy though.

Works fine for me, too. XP1700+ & nForce 1 (onboard video and sound). Neat little game. :) Did it take you long to program? I'm curious because I've yet to gather the will to try a 3D version of Transport Tycoon. ;)

It took about 5 months, but it's hard to estimate how much actual time. Some weeks I spent a lot of time and other weeks were slower. I should actually read we since a friend also worked on the game. Someone with more experience coding games would have been able to wip out a game like this in much less time.

I also bought a PS2 about the same time we started the game so I had to divide my time accordingly. :wink:
