Grenade
@everyoneDo you want to make some kind of grenades in your game? I've got you here pal!
Put these lines of code into your loop_script:
//BOMB THROWING LOGIC
player check rotation rotx roty
degtorad=$roty
degtorad-=45
degtorad*=0.034906585
global.bombthrowy=SIN($degtorad)
global.bombthrowx=COS($degtorad)
global.bombthrowx*=-15
global.bombthrowy*=-15
degtorad=$roty
degtorad*=0.0174532925
fixbty=SIN($degtorad)
global.bombthrowy+=$fixbty
degtorad=$rotx
degtorad*=0.0174532925
global.bombthrowf=SIN($degtorad)
global.bombthrowf*=350
global.bombthrowv=COS($degtorad)
global.bombthrowv*=-350
global.bombthrowv+=80
global.bombthrowz=COS($degtorad)
global.bombthrowz*=-21
global.bombthrowz+=21
21 = player height divided by 2.
15 = player radius minus one plus grenade radius (works best when it's zero).
350 = throw force.
Use this frame into FSM:
frame 0 0.01 0 0 0 SPAWN fbombprj $global.bombthrowx,$global.bombthrowz,$global.bombthrowy $global.bombthrowf,$global.bombthrowv
"fbombprj" - is an enemy with zero radius that does nothing and act as a throwable object, since decorations don't have any physics.
Pros: Now you have a means of throwing stuff. It even takes into account if you look up or down.
Cons: To prevent spawning things through walls when you stand next to them, we have to spawn things one unit inside player's radius. It pushes back a little, barely noticeable while in movement. But if you make your projectile radius bigger that zero - pushback is much more noticable. By tweaking the 15 number - you can increase the pushback even more without changing the projectile radius.
