| 3 | \brief a weapon that a player can use |
---|
| 4 | |
---|
| 5 | A Player has a list of weapons, that can be choosen to shoot projectiles |
---|
| 6 | (projectiles.{cc,h}) at ennemies. These weapons can be shooted sequentially |
---|
| 7 | or (if able) combined. Therefore you can choose the weapon mode = choose |
---|
| 8 | a weapon. |
---|
| 9 | |
---|
| 10 | A weapon is characterized by: |
---|
| 11 | o firing-rate: the initial firing rate of a weapon (1/s = Herz) |
---|
| 12 | o slowdown-factor: this is a factor d: exp(-d*x), d is element of all positive R. it determines how fast the firing-rate will slow down. if no slowdown: d=0, the bigger d is, the faster the weapon will slow down! |
---|
| 13 | o energy-consumption: this determines the energy that has to be used to produce this projectile = costs per projectile |
---|
[4597] | 14 | |
---|
[3573] | 15 | Furthermore there are some other attributes, that will help to represent a firing |
---|
| 16 | weapon in this world: |
---|
| 17 | o sound file/ressource: this is a pointer to the sound-file/ressource. however it may be represented |
---|
[3575] | 18 | o shooting animation |
---|
[3862] | 19 | |
---|
[4597] | 20 | |
---|
[3862] | 21 | a player defines one or more weapon configurations. a player has got one to eight |
---|
| 22 | weapon slots: places where weapons can be attached to. a weapon configuration |
---|
| 23 | is a matching between weapons and slots. |
---|
| 24 | Since its clear how many weapons a player will have, there is no list of weapons: |
---|
| 25 | its hard coded and limited to 8 slots and 4 configs. More would be a waste of |
---|
| 26 | memory and time you need to customize and change to a weapon config... |
