Collision_line function?

[Octohunter]

Hey all,
I was just wondering if there was an existing function that would allow the game to detect whether there was a solid object between two points.  I'm in the process of coding a ranged weapon system, and I'm just about done except for the actual bullet and this.  Any help would be appreciated :)

I don't believe there is a preexisting one. But making one shouldn't be difficult. Run a loop that goes through all the tiles in the direction the player is facing that checks for blocks and other players.

That's not how my ranged system works, though. Basically, you target an NPC and press the attack button.  If you have a ranged weapon equipped, it will hit the NPC if it is in range.  What I want is to program a function that will allow the game to detect whether there is a solid between the x and y coordinates of the player and the x and y coordinates of the npc. Thanks, anyway.

Then run a function to check whether there is anything between X1,Y1 and X2,Y2 :) Or rather, write one.. There's plenty of material around on google for this stuff in Grid Based games, I'm sure you can find some base code for it. ^^
