Mouse Tank - SierraKen - 01-21-2025
Here is a game I've been working on for a few days called Mouse Tank.
You use your mouse to move your little tank anywhere on the screen while dodging the monsters and shooting them
with your left mouse button. Also you can turn the turret cannon using your mouse wheel.
I know B+ made something similar to this years ago but I realized that half-way into making it.
I hope you all enjoy it. I had a blast making it.

RE: Mouse Tank - bplus - 01-22-2025
Neato except every Basic game I've played I shoot with spacebar.
It's such a habit I disabled the Inkey$ detection, you have escape built into ending the main loop so there is zero loss of function.
This is allot like eRATication except no cheese
RE: Mouse Tank - SierraKen - 01-22-2025
Thanks for the suggestions B+. You are right, the Space Bar shooting is much more fun, so I added that, but also kept the mouse button firing as well in case people are already wanting that instead, or if people want to switch. I also changed the pause and un-pause to Esc and made Q to quit. Plus I fixed one line where people kept having to turn the gun turret at the start of each level from pointing up to wherever they want. Instead I kept the angle of the gun turret the same as the last level.
Much more fun now!

RE: Mouse Tank - SierraKen - 01-22-2025
Here is a video I made of me playing it.
RE: Mouse Tank - Jack002 - 01-22-2025
Cool game.
So this has scoring and lives?
RE: Mouse Tank - SierraKen - 01-22-2025
Thanks Jack. No, just 1 life, but it has a health percentage. You might be reading "levels" that it has.
RE: Mouse Tank - grymmjack - 01-22-2025
@SierraKen well done! Great job on your game! Great job on SHARING it this way.
Screenshots make shares much more compelling to check out IMO!
Will give this a go
RE: Mouse Tank - grymmjack - 01-22-2025
Very cool game so far. I know you are using the wheel for turret, but the game is painful to control with the wheel, imo
If it were slower, maybe we might have a chance with that method of control.
It would be cool to see this using joystick dual-stick kinda shooter style like MadTV, etc.
Left analog stick = move tank, Right analog stick = aim.
Adding controller support would be a fun challenge perhaps?
Regardless, good job on this. The sound effects leave a little to be desired. There are new things in QB64PE where you can use custom waveforms and stuff built into the SOUND command. Check it out! consider trying noise for explosion, etc.
From wiki: SOUND page.
Code: (Select All)
Optional parameter waveform& can be one of the following:
1 for square waveform (default)
2 for sawtooth waveform
3 for triangle waveform
4 for sine waveform
5 for white noise
6 for pink noise
7 for Brownian noise
8 for LFSR-based noise
9 for pulse waveform
10 for a waveform defined by the _WAVE statement
