Use SPHITSP to find the control number of the sprite collided with. If you are trying to find collision between one specific sprite and many others which aren't so specific, using SPHITSHP(Control Number, First CN, Last CN) works well, where Control Number is the specific sprite's number, and First CN and last CN are the range of numbers to allow returning collision from.

Also, SPHITSP must either be used in an expression or assigned to a variable. Otherwise it just returns a syntax error, because nothing is being done with it's return value.

Thanks! Is there anything I have to do with SPCOL and SPCOLVEC?

Grr, forgot that too! Yes, SPHITSP will not work without caaling SPCOL first. I'd recommend defining SPHOME for a sprite first, then calling SPCOL CN,HX,HY,EX,EY,TRUE - where CN is the Control Number, HX and HY are the NEGATIVE SPHOME offsets, and EX and EXY are the width and height of your sprite. TRUE will adjust the collision for SPSCALE.

Another mistake! It's EY, not EXY. Also, I mean take the SPHOME offsets and make them negative simply by going (-X) or (-Y) in your parameters for HX and HY. Also, I've never needed SPCOLVEC, I'd only use it if you want a specific speed of collision allowed only.

Thank you so much!
